[kalthalior]

Hmmm, interesting question. Back in the dark ages of my role-playing days (the original D & D, not advanced D & D), my first character was a fighter named Ragnar.
He was dubbed Calthalion (means to shine strong/dauntless in Quenya) by an elven NPC run by the DM (he loved Tolkien, almost every human character got an elven moniker, like Gandalph was Mithrandir to the elves), so he became Ragnar Calthalion.
After doing some Tolkien research of my own, I changed it to Kalthalion, and years later tweeked it to Kalthalior in another fantsy RPG to denote the title "High/Supreme Commander". Been using the Kal part for some time now in other games/forums - if you see Kalad & Kalax it could be me.
