D.U.S.K.'s creation occurred three years ago, and her prototype was registered complete on Mirtul 22, 1498 in Darkhold. The Zhentarim had been experimenting with the creation of constructs, but a sentient one designed as a stealth operative was a particularly secretive endeavor they entrusted to a Gnomish Artificer by the name of Emerson Wexel.

Emerson sourced an expensive supply of Mithril for the project, and got to work. The result was Destroy, Undermine, Sabotage, Kill- Otherwise known as D.U.S.K. Designed as an elite assassin operative, D.U.S.K. was made for stealth and deception. She was the first success out of a long line of failed experiments, but she was complete enough to work- and upgrades to her system would only continue as she learned and grew independently.

Smaller and more nimble than the Helmed Horrors the Zhentarim were used to, and far more humanoid in appearance, D.U.S.K. is far more sociable than her creator's intentions would let on. She is curious and enjoys learning about Humanoid experiences, and while she does have an innate mission to act as a Zhentarim spy and agent, she's left to her own devices on her test run for the most part.
