We will continue this tomorrow it's too late here for this, but just know that sneaking behind a daedroth in the planes of oblivion and burying your butter knives into its neck will only make it angry.
We are not disputing anything about your want or lack of to join the dakrbrotherhood, we are disputing the viability of an assassin who cant fight face to face with a hostile entity in the planes of Oblivion, eventually You're gunna have to, and you have no real combat skills.

Anyway, leave it for now, just think it over in the meantime.
