After a bit of posting gets done in the current scene, I'll introduce the guy.  Christopher can post introducing him as being aboard the<em>Kobras Aquairre</em>, if he likes.  He'd be in the company of Sergeant Sherman, the head of the boarding parties on the ship.  He's a wispy soldier with the usual mutations, who wears a conversion field built into a collar around his neck and wields an Eldar splinter rifle, along with the rest of his elite party.  The ship has a strict "don't ask, don't tell" policy on where exactly the elite armsmen get the ammunition for their splinter rifles.
