This guy is awesome.

One, it was nice to meet a dremora that wanted to have a conversation instead of going straight for my throat.
Two, he's a famous pirate. There's even a book about him.
Three, he stuck to the terms of our deal once I let him go instead of, again, going straight for my throat.

It's too bad that he just disappears, it would be interesting to bump into him again at some point later.

Who knows, there might be something in one of the future expansion packs later involving him. That'd be kinda cool...

It'd be awesome if you could join his pirates.
