Nightshade
Gnosis 5
This Talen is distilled from the very essence of night. When quaffed, one fluid ounce of this liquid turns the imbiber's body into shadow, rendering her virtually invisible in darkness. Only a watcher searching actively for the user can make a roll to spot her. This effect lasts only an hour. Weaker versions of this Talen exist that last only until the change of the next hour.
To create nightshade, a spirit of night or darkness must be bound into a vial.
