Black Vestige

A large, black, seemingly Draconic clawed hand, the First Vestige was discovered being used by Adair of Storia and The Black Talon, who were somehow able to harness its power to resurrect Dragons of various kinds.
It seemed to be somehow linked to Beatrice Wyrmwater, able to control parts of her body when moved, and vice versa.
Arabella Whitby was seemingly able to remove the link between the vestige and Beatrice, purifying and destroying the strange, black energy that it bore, while absorbing the glowing white energy into both the Purifier and partially into Beatrice.
