My (old) vampire Nord character is named Brigid, though she also has a dragon name: Briivulonkulaas which means "Beautiful (Brii) Night (Vulon) Princess (Kulaas). Her reasons for being a vampire is to "become as close to a actual dragon as humanly possible" and also so she can "cheat the system" and prevent Alduin's eventual return after his defeat (cant destroy the world as long as the dragonborn exists). She actually loathes Molag Bal, seeing rape as worse then murder. She worships Herma-Mora because she believes knowledge is power. She is a master in Restoration, Conjuration, One Handed, Heavy Armor, Archery, Pickpocketing, Lockpicking, and Speech. She kills because thats what she was born to do. She loathes the use of "mortal cattle", as to her it is laziness. She believes vampires are suppose to be hunters, going out into the night, taking only what they need, and returning without anyone the wiser. She believes its foolish and arrogant to try to assert dominance over the mortals and also foolish to try to gain acceptance from them. Now, in charge of the Volkhair clan, she hopes to "whip these pampered b**ches" into shape.
....sorry about the story.
My current one which im gonna start soon is also named Brigid but is a member of Dawnguard.
