Canoptek Wraith
These are some scary Snake mother fuckers. Did I mention they are the Grilled Cheese Sandwich of the Necron Codex. They Slither over everything, and have a 3++ save. They are basically faster Lychguard. Did I mention these guys are basically Necropolis Knights or Sepulchers from the Tomb Kings (rip. may your sleep be blessed). Besides that their is not much I can say. Here is a picture of a snake for you. Oh wait, I can't figure out how to add photos, Fuck.
