Thousand Sons marine. Once of the original raiders. Commands a raider-sized (i.e. small, much smaller than the original Maiden for example) transport. Motley crew of humans from all over the Segmentum. They seem to serve him quite willingly - and in return he's quite protective of his little flock (to the extent that he's killed several people, including another Chaos champion due to incidents related to his pack). Not much of fighter (apart from being a space marine that is). He's more into experiencing the world. He doesn't seem into the darker excesses so many of his brothers crave, which may indicate that he's fairly young (but Castor is fairly sure he actually pretty old).
