Obsidian Pendant

Sight in the dark, bought with the warmth in your heart.

A lump of impossibly black volcanic glass strung on a leather cord. Nearby light dims around it, and kindness seems subtly sucked away.

When you wear it openly for a few minutes, your eyes see clearly in all but pitch darkness, but your instinct becomes Callousness: to disregard others' feelings, needs, or wellbeing.
