Necromancer

You nearly laugh at the idea that ANY of these beings are your "allies". A more appropriate designation would be "The folks who are currently on your side because it's advantageous at the moment". Velzix doesn't trust any of them despite the fact that they all knew and worked with each other in the infernal plane. (Actually he doesn't trust any them BECAUSE of the fact that they all knew and worked with each other!) Given that fact, you probably shouldn't either.

Better keep your attention on them because as they say "Keep your friends close and your enemies closer"
