Heh...I'd link you to the character sheets if I still had them online.
in D&D 3rd Ed Seloce is currently an errant knight (fighter class) seeking an exiled scholar to help return his liege to his proper throne.
in Shadowrun, Seloce is a doomed elf from Tir na Nog engaged in a belittling downward spiral of drugs, pain, and misery. interesting character there -- he commits suicide in his character bio...all the games I play him in are "flash backs"...makes for a really cool effect. he was in the public play (pre-release) of Brainscan, which was run by Jay Levine who is one of the writers for now defunct FASA.
in Mage Seloce is a Euthanatos vagabond, a slave to the wheel of fate who lives (or comes close to not living any longer!) by the roll of the dice, the flip of a card, or some other method of pure chance.
in Everquest, seloce was a 60th level shadow knight.
in Dark Age of Camelot, Seloce was a 48th level scout who was the bane of many a middy and hibby before Mythic made all of those *wonderful* game changes that totally screwed all snipers. if you don't know what I mean, read this
...as it is a wonderful example of what not
to do as a game developer.
For the most part that's all of them. there have been plenty of other incarnations of the name, but I don't think you want me to go on for much longer. hehe.
