[@AtomicNut] We're still accepting but there are a few issues. Firstly, the only people who have ever survived going near Old Valyria were (possibly) Euron and his crew. Everyone else has disappeared or died. Attempting to travel there is a feat reserved only for the truly foolhardy, bordering on insane. A random mercenary company would not make the attempt because any profit would have been overridden by the enormous losses and the extremely minuscule chances of returning. Simply sailing by the place is usually death, stepping on there would be all kinds of hell. 

Secondly, the only ones who've so far managed to take control of dragons are the Targs. Any lone person managing to hatch a dragon would have caused a massive political shitstorm as everyone in Essos immediately tries to capture or kill the dragon, which they very well could if it's still in adolescence, and the Iron Throne tries its damnedest to track down the rider to make sure they aren't a threat. For story reasons, right now the only dragon riders are part of the Targ dynasty or closely tied to it. If you want your own dragon-riding character I would suggest you could play Aegon Targaryen or his children, since Aegon is the rider of Viserion. Since he is living in Dorne now you could even explain him having such martially inclined children that way. 

Other than that the sheet looks fine. 

[@Masterkeun] That's fine take your time.
