Jabberjabber over at Warpstoneflux posted earlier this week about Daemon name generators, used to help you with ideas for naming your daemon's to fluff up your army. Pretty cool, and like he says there used to be one on the GW website that I can't find either.
But, what if you're not a servant of the Ruinous Powers, and what some ideas for naming your Space Marine captain, your Cannoness, your Comissar or your Inquisitor? Well, over on the Dark Heresy website, there's a name generator for generating Imperial Gothic names for either gender, in different formats. Try it if you need some inspiration for naming your Imperial characters.
