There's a small handful of names that I use.
Malaclypse - from the Principia Discordia, also the name of my Paladin on Arctic MUD (back in my mudding days).
Harowen - From Angband, Harowen the Black Hand, primary name I use for rogue's. Also most likely to get nerfed.
Aule - Aule Kementari, from the Silmarillion.
Krindi - From David Weber's Empire of Man series.
