A strange liquid that allows Umbra to transform into her shadow form.
She discovered the substance while exploring an ancient temple thought to be used by demon worshipers of the Ulrek Cult. Unexpectedly swallowing some of it when she fell into the vat, she experienced her first transformation into the Shadow Demon.
Ever since then, she has protected the fountain with a special barrier that only she can penetrate allowing her to return and refill her supply as needed.
Little is known about it’s origin or the long term side effects of ingesting it.
