I might RP a hobbit in LOTR online, but most definetely not in Tamriel. Oh, and Bosmers aren't that small or harmless. Try reading "A dance in fire" sometime.
Sure, and I play a Bosmer so I know your right, but sometimes after you've made a few "serious" characters its cool to just screw around a little and have some fun.
I made a "Native American" Redgaurd in Oblivion that was a kick in the pants. (long hair, war axe, marksman, and fur armor) He just rode around hunting and raiding Imperial settlements. (of course I had the right music too)
I also made a blue(ish) faced bosmer that I called Dwarven as well.
edit: And of course they don't belong in TES, but its a fantasy world so I feel free to fantasize just for fun.
