I have a few characters that I made relatives of other characters that I have made. This game is so big that (except for my usual grind of ridding the area around Whiterun of bandits to get to LVL10) I haven't had much problem of characters running into the same quest unless I choose to do it myself.

Nice that you like it guys! It is really fun so far and can't wait to fight on horse back and smash in the imperials while doing the cw questline ^^

You could be Ulfric rejected/forgotten/unacknowledged brother, maybe half-brother. Perhaps even a "traitor" and supporter of the legion. Make believe is fun, who wants to play guns!!! PEW PEW!

Relating your toons to NPCs is fun. (: It's nice to feel like your character isn't all alone in the world, ya'know? I made Balimund my Nord's brother, so whenever she stops by Riften she makes sure to pay him a visit. My Khajiit, Dar'Shavir, has kin in Skyrim as well: J'Kier and Ra'kheran, who died hunting down a werewolf ('Ill Met By Moonlight' ring any bells?) and Ma'zaka, the keeper of the Solitude lighthouse. Ma'zaka always tells him to leave whenever he stops in for a chat, though, so Dar'Shavir doesn't pester him too often.
