Amethyst

As you pull back the curtains, a flood of daylight pours into the room, illuminating dancing dust-motes and filling the old attic with glorious golden light. A squirrel scampers away into a dark corner, and you realize with a laugh that it had been the mischievous rodent who'd scared you so badly! You turn to go back down, but an old, intricately carved wooden chest catches your eye. It is locked, but the lock looks rusty and can probably be broken or picked easily.
