Overview

Hollowspire is beset by a creeping seasonal gloom that threatens the town’s harvest festival. Deep beneath a ruined watchtower lies the Hollowspire Vault, home to the Sun Dial – an artifact that once tempered the seasons. Five adventurers are hired to descend, retrieve the Dial, and reactivate its wards before the next moonrise.

Adventure Structure

A compact dungeon designed for five 1st–3rd level characters. It features a hidden encounter and a decisive ending that shapes future threats in the region. Expect puzzle-solving, careful exploration, and measured combat rather than brute force.

The Dungeon (key rooms)

• Room 1 — Entrance, The Sealed Stair: A collapsed mine mouth leads to a rune-locked door. Three sigils must be aligned by discovering clues in nearby carvings (Investigation DC 14). Failure triggers a minor illusion and a sparse trap.


• Room 2 — Hall of Echoes: A 60-ft corridor whose walls imitate whispers of the party. A Perception check reveals a rhythm to step in and a pattern that opens a hidden door to Room 4.


• Room 3 — Guardroom of the Silent Watch: A toppled statue guards a chest. A hidden mechanism requiring a page from a mural rebuilds a barrier and frees or awakens the statue for a riddle or light combat.


• Room 4 — Hidden Vault (Hidden Encounter): Behind a false bookshelf lies a concealed chamber containing the Earthbound Warden, a bound earth elemental sworn to guard the Dial. Diplomacy or mercy can grant aid and reveal safe paths; attacking provokes a stern counterattack.


• Room 5 — Chamber of the Sun Dial: The Dial pedestal sits within a ring of wards. Activating it seals the gloom and rewrites the fate of Hollowspire. The ending hinges on choice: reseal the vault and safeguard the Dial, or tempt time-magic and invite unpredictable consequences.

Hidden Encounter

The Earthbound Warden is not initially hostile. If treated with respect or offered a token from the outside world, it unlocks the vault’s true route and grants a single-use boon (advantage on a save, a clue to the vault’s history, or a bypass for a trap).

Ending & Rewards

Returning the Dial restores the warded seal and lifts the gloom—townsfolk celebrate, and the party receives the Dial’s mundane-to-mildly magical powers and treasure (gp, scrolls, potions). Opting to tamper with time carries risks: a wilder seasonal cycle, or a future threat hinted to the party by a cryptic rune. The finale seeds future quests, whether for calm renewal or deeper mysteries beneath Hollowspire.
