[@Lucius Cypher]..............
I said at the beginning of all of this that every "boss", was still existent, especially a few of the ones that would be integral to this roleplay, like for instance, Artorias.
You're saying that this man has singlehandidly done much of what the Chosen undead has done [b]despite[/b] the fact I said this was prior to those events you've took it upon yourself to fill those boots as if it was an invitation; well from what I gather of the story you actually killed who the main protagonist was meant to be.
Not only that, but you've acquired the Lordvessel, although you later "misplaced" it the fact that you even acquired it is nonsensical; there's no way I'm allowing most of what your character has done.
The search for Queelag is one thing, that you can go ahead and do clearly your character has some sort of obsession with the chaos servants, and that's alright.
That's a story you can do without piggybacking on the games actual story and calling it your own. 

Your character sheet is well developed and I like the direction you are going with his personality and on the brink of despair, but I can't allow this Character sheet as it is; I'm sorry to say that you'll have to omit a great deal from the Bio to make this character of yours viable.
This is a roleplay about the dark souls universe, but that does not mean we are playing it as if it is the game.

Pm me if you want any help or a discussion on what to do from here.
