Location: Belladonna - The Cottage of Onyx

Onyx's Cottage

Exterior Description

On the mossy northern edge of Belladonna, nestled against the treeline of Whispering Pines, lies Onyx’s cottage. At first glance, it appears to be a humble dwarven stone home built into the hillside — a moss-cloaked roof, rune-carved chimney puffing smoke, and ivy creeping up the iron-latched shutters. A solitary birch tree glows faintly in the moonlight, leafless and watchful. Protective runes encircle the grounds, creating a subtle barrier. Any creature with hostile intent must succeed on a DC 15 Wisdom save or involuntarily turn back in dread. Beneath the windowsill, smooth fist-sized stones inscribed with celestial runes glow and shift color depending on the alignment of those nearby.

Backstory

Once the Archon Adonais, guardian of mortal choice, Onyx sacrificed his divine form to seal away the demon god Yaldaboath. Rather than fade, his essence reincarnated in mortal flesh, sleeping between ages. As Onyx, he serves quietly as Belladonna’s elder cleric of the Old Light. But he has begun to dream again — visions of the Ash Eclipse, a sign that Yaldaboath stirs once more.
