To those of you unfamiliar with the concept: A bloodline is your own story woven into that of The Elder Scrolls. It revolves around the idea that the characters you play in each of the games descend from each other (missing generations if time need be)
It can be anything from an excuse to play with a class you like to making personal mods for them (something I did in Oblivion- was only a little house though )
For example: My bloodline is that of the educated Breton battlemage. The main family home is in an idyllic location overlooking Illiac Bay. All the children of the large household train with sword and spell, and study with mind and body like their parents before them. They are highly trained warriors and their coming of age ritual is to wonder Tamriel (where they come into the games). They have spawned many legends - legends that only survived because of their prior conditioning and training. (I mean- come on- would you still be standing after a fireball to the face?)
But enough about me
