Overview: Mistwood Valley hangs between dusk and dawn, and a tranquil village named Glimmerhollow relies on the Ember Ward, a protective shimmer powered by a sacred Ember Crystal. When the crystal is stolen during the Harvest Moon festival, the ward falters and the borders between realms grow thin. This short, easy arc is designed for 3 players at low levels (1–2) and can be completed in a single session or two compact sessions with a light, heroic tone.

Setting and tone: The campaign blends rural fantasy with gentle mystery. Glimmerhollow sits at the edge of Mistwood Forest, near Emberspire Crag. The town is charming but tense as sickly fog leaks from the forest and curious fey begin to probe the wards. The artifice workshop of Dowel Nettlewright is adjacent to the town square, offering both aid and mischief in equal measure.

Main quest: Recover the Ember Crystal and restore the Ember Ward before the dawn of the next full moon. Once the crystal is back in its reliquary, the ward can be reignited, sealing Glimmerhollow from mischief until the next season.

Core locations:
- Glimmerhollow: the innocent-seeming village, home to the missing innkeeper’s daughter, rumors of a secret cellar, and the town councillor who sponsors expeditions.
- Mistwood Forest: a maze of silver-leaved trees with hidden fungal groves and watchful sprites. Easy environmental hazards and minor fey tricks.
- Emberspire Crag: a defensible ruin with a cracked observatory where the Ember Crystal was last seen; home to a quiet, misled ex-apprentice, Lirael.
- Goblin Den and Dowel’s Workshop: optional tangents for clues and gear.

Key hooks and side quest: A local innkeeper pleads for help finding her missing daughter who vanished after a quarrel with a traveling peddler. Investigators who follow leads into Mistwood Forest may discover a hidden cellar beneath the inn, filled with stalked barrels and a temperamental guardian golem who remembers the night the crystal was stolen.

Antagonists and twists: The culprit is Lirael, a former artificer’s apprentice who seeks to power a crude machine using the Ember Crystal. Her motive is personal and misguided, not purely evil, making a few peaceful solutions possible if players choose diplomacy over violence.

Encounters and challenges: three to four gentle combat encounters with goblin scouts and forest guardians, plus a puzzle in the Emberspire Crag that requires a simple alignment of wards. A social scene with Dowel Nettlewright can yield a safe alternative to force, and a timely rescue of the innkeeper’s daughter can unlock a powerful ally and a shortcut to the final confrontation.

Main objectives and rewards:
- Recover the Ember Crystal and reignite the Ember Ward, restoring protection to Glimmerhollow.
- Stop Lirael’s plan and save the town from interplanar mischief.
- Rewards include the restored ward’s gratitude, a minor magic item (e.g., Cloak of Warmth or Ring of Purity), a modest sum of gold, and a permanent +1 to a skill tied to whichever path the players pursue (arcana, nature, or stealth). The Ember Crystal can be used once daily to boost the ward for a short period afterward.

Campaign flow: tight, clear objectives with optional paths for exploration or roleplay. Perfect for new players and a quick, satisfying conclusion without sacrificing narrative depth.
