... Okay, um... this is a former holy order of knights dedicated to the defense of Thaln and its people.

Your character is a former cannibal and mercenary.

He needs a VERY good reason to be allowed into the knights. Also, he would only have heard of them after arriving on the continent where  Thaln is located on... and probably getting relatively close to Thaln as well.

He's not a Knight Errant like a couple of the other characters are, he's not someone who was taken in by someone who could shuttle them towards the Iron Rose Knights. And he's not nobility or a knight of Thaln who wanted to join them.

He needs a [i]really[/i] good reason to be part of them, especially given his history.
