Sigrun War-Blade is my main Skyrim character, a Level 45 female Nord in full Dragon Armor who I tend to keep around the occasional high-level skulduggery and for the pleasures of burning my fuckton of cash on all of the Hearthfire houses. A Cyrodiil-born Nord, she crossed the border to reconnect with distant family members in Helgen - but didn't expect to end up saying hello from the back of a cart of prisoners of war...
I also have Red-Scale, a Level 32 Argonian sneak-thief who's a bit more morally defensible than my third and last character to date. Red-Scale takes pains in order not to kill anyone, but his past as a Shadowscale means he's still rather proficient at it. He's been petitioned by the Empire to try and cripple the Thalmor and Stormcloak agendas by any means, and is a deniable asset in every sense of the word. While he could've escaped his execution, his nature as an unrecognized operative meant his only authorized recourse was to die. That's obviously changed for the better. Or is it for the worse?
I see him as being a little less able to digest the Dragon Blood's burden without getting a case of the inflated head.
Hassan is a Level 25 Khajiit assassin whom I use largely as a stress relief device. I pop his save files in, start the game, kill a few people, exit the game without saving, recompress his files, and I'm done. He's my stress ball, more or less. Considering this, he's pretty peachy about being the Dovahkiin. More power means more killing, right?
He considers himself an artist with a pair of daggers and the cover of shadows, and could more or less be considered to be a self-absorbed but highly functional comparable to Cicero.
My main Fallout 3 character was called James, mostly because I figured him having the same name as his rather important father would be a nice touch. My female was called Kate. They were both Speech and Small Guns specialists.
For New Vegas, I settled with Madeleine Smith - shortened to Maddie - because I felt like playing her as a physically capable Femme Fatale. Half Mona DeMarkov and half Beatrix Kiddo, more or less. Highly calculative, always a bit hazy in her motivations - but never a monster by any stretch of the word.
Oblivion's almost always seen me use an Argonian called Red-Scale, who may or may not have been the ancestor of my Skyrim Red-Scale.
