"Cancer"

"Cancer" is Mahdi's Nosferatu contact and ally. Mahdi reputedly pays Cancer a great deal of money for his access to local information networks, insight into the Nosferatu undercity, and abilities in general as a spy. Augmented by his virtuoso-level abilities with Obfuscate, he can not only disappear, but encourage others to forget he was ever present. His moniker comes from this - they look very much like the claws of a crab.
