There are those who would brand the practitioners of the necrotic arts as unholy villains without a second thought, but their unorthodox practices have actually inspired more than a handful of useful advancements in other fields. This tattoo, for example, was the product of an artist’s short- lived fascination with necromancy, as they were compelled to find a design that would draw out the life force of a target and channel it into the tattoo’s bearer. Eventually, they found a way to do this without requiring the bearer to bite its target, which was quite the accomplishment.
