It's about rules and boundaries. A set of rules that you, the player must conform to that ultimately define your character's personality.
Kalin is a mage, not a soldier. So if I were to RP her, I would not join the fighter's guild (for example). She is a book-worm, and a student of magic. I would take care to learn every tome of magic I find, and to glance over the more interesting tomes I discover.
She's lawful, she's no thief. Stealing is wrong, Kalin will not do it.
Kalin is has a gentle heart. She will not take a life of another, save for in defense of herself or the good people of Skyrim. She will attempt to talk my way out of any situation first, when ever possible. She would pay the brigands their 100 gold tax to use the road.
If it comes to blows, she hates resorting to violence herself. Relying instead on her companions, or her enthralled elementals to dispatch her foes. In the most dire of circumstances, she will invoke devastating illusion and destruction magiks on an expert or greater level.
Kalin, in pursuit of her studies into the arcane, has allowed herself to become a vampire. She naively insists that "her condition" (as she calls it) will do nothing to alter her personality.
She has since been expelled from the college of Winterhold, she may not return.
She performs all of her research from Honeyside Manor in the Rift. As a result it is like a home to her. She still refuses to kill, even to feed. Which she does so reluctantly every three nights.
Her condition as a vampire, and her reluctance to kill, has put her in an tense relationship with the Vigil of Sendarr. The Vigilant patrol the roads of Skyrim, especially int he Rift. Kalin sees them as goodly folk who bless the cursed, heal the wounded and keep safe the road of thieves, beasts and vampires..
Vampires like her. She will take care to help the Vigil whenever she finds them under attack.
The Vigil, however, return her assistance by assailing her! She will now allow them to force her hand, instead she paralyses any aggressive vigilant. She will destroy their attackers, make sure the road is safe before receding into the night. The vigilant of Stendarr awaken some time later. Groggy, confused, with a headache, but alive to continue their good work.
So. The game is Kalin of High Rock. Here are The rules!
