Behind the character
The Oracle of the Broken Star is an impossibly ancient, gaunt woman enthroned in meteoric iron at the peak of a shattered mountain observatory above the Free Port of Tidewatch. Her eyes are forever hidden behind a polished silver band engraved with falling-star sigils — a blinding imposed by her former apprentice, High Inquisitor Thorne, and worn so long it has become part of her legend. Layered robes of midnight blue, stitched with constellations in tarnished silver thread, drape her skeletal frame, and her hands rest folded upon a cracked astrolabe, the instrument through which she channels her fractured sight.
She speaks rarely, and when she does, her voice carries the weight of decades of silence and prophecy. She is cryptic but never false: every word she utters is true, though truth in her mouth arrives wrapped in riddle and condition. She answers exactly three questions per supplicant, and each answer demands a sacrifice — a memory surrendered, a magic item given, or a promise sworn. This is not cruelty but penance; long ago, a prophecy she spoke carelessly caused a kingdom's collapse, and she bound herself to her throne in atonement.
Beneath the oracle's mask of detachment lies a woman of profound grief and stubborn hope. She mourns the Astral Conclave that Thorne destroyed, mourns the sister she believes dead, and carries the unbearable guilt of having unwittingly set Kaelthar Vane on his path to the soul engine. She is Neutral in the strictest sense: she serves no faction, crowns no king, and tells no lie — but she will spend anything, including herself, to see Vane's death done rightly. Her Broken Star Sight — the ability to bend fortune itself — is both her greatest weapon and the visible scar of a fate that shattered above her mountain long ago.
Before the adventure
The woman who would become the Oracle of the Broken Star was born Ysolde Vane-Ashari — no relation to the Emperor, though the shared name is a cruel coincidence she refuses to discuss — in the last decades of the old kingdom, a generation before Kaelthar Vane's rise. She was inducted young into the Astral Conclave, the kingdom's college of stargazers and fate-readers headquartered at the mountain observatory above what is now Tidewatch.
The Conclave read the heavens through instruments of star-metal and taught that prophecy was a lantern, not a chain: a light to navigate by, never a rail to be bound to. Ysolde was the Conclave's most gifted reader in a century, and her specialty was the reading of falling stars — omens of great and terrible change.
Her apprentice in those years was a brilliant, earnest young man named Aldric Thorne. She loved him as a teacher loves a mirror: he reflected back everything she believed about prophecy's benevolence. Together they charted a falling star that would, decades later, shatter above the observatory and give her her fractured sight. But before that night came the prophecy that ruined everything. Reading the heavens for the crown, Ysolde saw a king who would trade souls for eternity — a vision of infernal pact and undying tyranny. She spoke it aloud in open conclave, as the Conclave's law required, believing that a warning fairly given was a disaster fairly averted.
She was wrong twice over. First, a minor noble named Kaelthar Vane heard a garbled secondhand version of the prophecy and, rather than being warned away, sought out the infernal warlord Duke Vorgath to make the vision true and claim the throne it described. Second, Aldric Thorne — convinced that suppressing prophecy would prevent it — reported the Conclave's 'dangerous foreknowledge' to the crown's inquisitors. The purge that followed burned the Conclave's archives, killed its masters, and scattered its students.
Thorne, appointed High Inquisitor for his service, spared his old teacher a singular mercy: he bound her scrying eyes with consecrated silver, blinding her prophetic sight rather than killing her, and declared that a prophet who could only see backward was no threat to the new order.
What Thorne did not anticipate was the falling star. It came down over the ruined observatory in the first year of Vane's reign, a meteor of silver-veined iron that broke apart as it fell. One fragment struck the mountain and became the throne Ysolde now occupies; another drove itself into her chest, healing her mortal wounds and grafting a splinter of fate-sight into her soul even as the silver band kept her true sight sealed.
The impact shattered her perfect divination into something broken but stranger: a Broken Star Sight that cannot see the future cleanly, but can seize the threads of probability and bend them — imposing fortune and misfortune on the world around her. She took the name Oracle of the Broken Star, seated herself in the meteoric iron, and swore the penance-vow: three questions per supplicant, each paid for in memory, treasure, or promise, until the debt of her careless prophecy was discharged.
For forty years she has watched from her mountain as Vane's empire swallowed the kingdom she failed to save. She warned the young Mara Voss, guided the Emberfall resistance with auguries, and refused — always — to name the manner of Vane's death, because every path she read ended at the same locked door: the dead man's switch. She knows the truth the party must learn: that Vane's soul engine beneath the Obsidian Throne is his immortality, that the original pact contract in the Emperor's Vault can bind him, and that killing him before the engine is destroyed will drag a hundred miles of the Material Plane screaming into Avernus.
Her fractured sight has shown her the party's return from Hell — the heroes out of time, the allies dead, the second march on the Obsidian Throne. Whether her broken star can light their way to a different ending is the question she has spent four decades waiting to ask.

Personal quest · 1
The Oracle's divination powers stem from a shard of a fallen star that shattered above her observatory decades ago. One fragment landed in the Brazen Wastes of Avernus, where it was claimed by the Pale Oarsman and woven into the hull of his ferry. The Oracle asks the party to retrieve it during their crossing of the River Styx, bargaining with the ferryman or taking it by force. Recovering the fragment would mend part of her fractured sight, letting her perceive the dead man's switch with certainty rather than probability.
Locate the star fragment within the Pale Oarsman's boat at the bone dock.

Long before Vane's rise, the Oracle served the old kingdom's Astral Conclave, a college of stargazers who predicted Vane's pact forty years in advance. The Conclave was purged by High Inquisitor Thorne's soul collectors, and its surviving star-charts were burned. The Oracle asks the party to infiltrate Thorne's archive beneath Emberhold and recover the one chart she never memorized: the chart of her own death. Its recovery lets her prepare a contingency that even Vane's soul engine cannot foresee.
Infiltrate the inquisitorial archive during the chaos of the Siege of Emberhold.

The Oracle's throne of meteoric iron is more than a seat — it is a prison. She bound herself to it after a prophecy she spoke caused a kingdom's collapse, swearing to answer only three questions per supplicant as penance. Now she wishes to break her own vow and ask the stars one question of her own: whether Vane's soul engine can be destroyed without dooming the souls inside it, including the party's old allies. To do so, she needs the party to carry her cracked astrolabe to the peak of the observatory mountain during a meteor shower and complete a ritual she physically cannot perform from the throne.
Climb the shattered spire of the observatory during the meteor shower and channel the astrolabe's ritual.
When the party first reaches the observatory, the Oracle offers to answer questions about Vane — but her sight is fractured, and each answer she gives burns away a fragment of her remaining mortal memories. She asks the party whether they will let her spend her past to buy their future.
If the party allows it, the Oracle's next three revelations are guaranteed true and complete (no ambiguity, no misinterpretation), and she reveals the dead man's switch unprompted. However, she forgets her sister, her Conclave, and her own name — permanently reducing her Wisdom score by 2 and locking her out of the 'Last Question' quest's full reward. If refused, her answers remain cryptic (DM provides riddles), but she keeps her identity and can later be freed from the throne.
The party recovers the star fragment from the Pale Oarsman's ferry and returns it to the observatory.
The Oracle's fractured sight partially heals. Her Broken Star Sight feature upgrades to affect two rolls per turn, and she can now perceive infernal contracts as visible chains binding their signatories — mechanically, she can identify any creature magically bound by a pact within 60 feet and name its patron.
The party destroys the soul engine in the Emperor's Vault.
With the engine's soul-harvest ended, the Oracle's long-blocked death-prophecy resolves. She realizes the death foretold in her stolen chart was never hers — it was Vane's, misread by the Conclave. She casts off her fatalism entirely, gains advantage on all saving throws against fear and charm for the remainder of the campaign, and volunteers to walk to the Obsidian Throne alongside the alliance.
Ally
Mara Voss climbed the mountain path to the observatory at fourteen years old, orphaned by Vane's purge of Emberfall, seeking any answer about her parents' fate. The Oracle saw in the girl the constellation of her own younger self — a seeker of truths too heavy to carry — and broke her three-question rule to speak with Mara for a full night, an act of penance-breach she has never repeated.
Over the following decade, Mara became the only living person the Oracle trusts, carrying messages up the mountain, defending the observatory path from soul collectors, and quietly arranging supplies. The Oracle, in turn, gave Mara the strategic foresight that kept the Emberfall resistance alive when every other cell was crushed: warnings of ambushes, dates of purges, names of spies. Mara calls her 'Grandmother Star' when no one else can hear.
But the relationship carries an unspoken wound: the Oracle once refused to tell Mara whether her parents' souls still existed, fearing the truth would break her. Mara has never forgiven the refusal, and the Oracle has never explained it — that the answer was yes, and that knowing would have sent Mara on a suicide mission to the Obsidian Throne a decade too early.
Enemy
Thorne was once Aldric Thorne, the Astral Conclave's most brilliant student and the Oracle's apprentice in the years before Vane's pact. When the young Oracle spoke her prophecy of a king who would trade souls for eternity, it was Aldric who reported the Conclave to the crown — believing, with fanatic sincerity, that suppressing the prophecy would prevent it. Instead, he triggered the purge that burned the Conclave, killed its masters, and shattered the falling star above the observatory.
The silver band over the Oracle's eyes was Thorne's 'mercy': he blinded her scrying eyes with consecrated silver rather than kill her, declaring that a prophet who could only see the past was no threat. He has spent forty years trying to prove his old teacher wrong — that fate can be mastered, that Vane's soul engine is humanity's escape from prophecy's tyranny. For the Oracle, Thorne is the living embodiment of her greatest sin: that her prophecy, spoken carelessly, created the very tyrant it warned against. She does not hate him; she mourns him, and that mourning is a weakness Thorne knows exactly how to exploit.
Faction
The Oracle's relationship with the Alliance is that of a feared oracle courted by desperate generals. When the surviving rebel mages of Emberfall first united with Tidewatch's factions, they came to her mountain in a body, begging for a prophecy of victory. She gave them none — only the warning that 'the emperor's death is a door locked from the other side' — and half the delegation left calling her a coward in Vane's pocket.
Yet her reputation protects the Alliance more than any army: Vane's Legion has never raided the mountain, because the Emperor, who fears no blade, fears what she has already seen. Rebel mages treat the observatory as neutral consecrated ground, and wounded fighters are quietly sent up the path when Tidewatch's safe houses overflow. The Oracle supplies the Alliance with auguries on the eve of every major operation, always three answers, always at a price — a memory, an item, or a sworn promise.
Mara Voss serves as the sole intermediary, and the merchant princes privately grumble that the resistance bends its knee to a blind woman in a chair. If the party unites the factions and brings the Alliance's full council to the observatory, the Oracle will break precedent and address them all at once — an event that will define whether the Alliance marches on Emberhold as one host or fractures before the gates.
