Pretty simple, really. Back in the late 1980's, when my and my two older brothers were first playing Might and Magic - Secret of the Inner Sanctum (This was our first "real" video game, by-the-by), my eldest brother had this Party of the Gods. They were originally named after people he knew in real life, but they were changed at some point. The character that was named after me was changed to "Marrend".
Marrend was Sorcerer, probably and Elf (though that point doesn't seem as important). Since then, every sorcerer in a Might and Magic title that I've made was named "Marrend". Oh, uh, I guess I also use "Marrend" as a user-name on various websites/forums and my Steam account which I'm rarely on.
*Edit: In case you're wondering, no, that's not who my current avatar is supposed to be!
