Cool name for a warlock.

Hello guys what do you think will be cool name for a warlock ?
I'm planning to create warlock soon, but don't know how to name him. You see I really put much effort to choose nickname that I like seeing and pronaunce.

So far nicknames that I like but are taken:

Excidium - From latin meaning destruction, overthrow, annihilate, destroy. I got this name, but don't like my name to symbolize negativity.
Deadalus - in Latin it means skillful, crafty, smart. Also it is a famous mythodological character.
Callibus - again in latin meaning skillful.
Nemesis
Adroit
Cryptex
Lex - meaning law and order in latin.
Ashbringer.
Validus - from latin meaning Strong, powerfull, mighty.
