My nick isn't nearly so personal (and sorry for your loss BTW, i couldn't imagine how devastating that would be) It originally came from morrowind if i remember correctly, i whipped open the editor, listed the npc's and went about choosing or modding character names for my toon there and thus Cormoran Venim was born.
Though he didn't become special until i transferred that name to a star trek PBeM sim when i transformed him from a stealthy dunmer into the psychotic cardassian i know and love today. It was a nice chance to sim someone with absolutely no good side at all, he's xenophobic, sociopathic, conniving, destructive, brutal and many many more nouns. I must say i've never had so much fun simming a character than i did with him, and so his name stuck with me.
I usually use the name for my toons ingame whenever i play an mmog, in lotro cormoran was a much nicer character, if a little too fond of the local ale and pipeweed. But for STO i've decided to wait, i've messed around with how i could make him look in STO but i'm not actually going to use him until either a cardassian faction or a pirate faction are implemented. In STO he'll continue to be the worst example of cardassian that cardassia prime has to offer.
And that is pretty much it, i could go on about his escapades in the various sims i've had him in but that'd just get boring and this post has already reached the point of self indulgance, so uhh, that's it! :p
Once upon a time I played a PnP Superhero RPG. My character's name was Ravenstein. Then later I played City of Heroes and made a character based on my PnP character there as well. Then I played Champions which is where my Cryptic forum handle comes from.
