Damon Prytanis

Damon Prytanis is the name a Perpetual assassin used after he forgot the original. The Cabal recruited him after Iwo Jima and spent millennia pointing him at good men who were inconvenient. He called humanity mon-keigh without flinching. John Grammaticus at least pretended to like the species.

He died several times convincing Cyrene Valantion she was immortal, then walked her into the Cabal. On Macragge he helped the fulgurite plot against Vulkan and stuffed Konrad Curze into a daemon-flask when the Night Haunter got too close. Loyalty to Slau Dha was the whole personality.

Eldrad decided the Cabal's victory condition was an Aeldari funeral. Narek broke Damon's neck and, while the immortal tried to climb back into the body, put fulgurite through him. Some deaths are administrative. That one was policy.
