The Orb of Souls
This glass orb was found in Aven Ro’s study. Dark shadows swirm inside it. Detect magic shows moderate auras of Divination and Necromancy
An identify spell has determined:
The orb has two specific functions. It seems to be able to detect the location of a shard of a particular shattered soul. It requires multiple uses over an extended period of time to narrow down the location. Then it allows someone who has absorbed one of those shards to access some of the greater functions of the soul’s owner.
