[@Klomster] A gellar field is not mandatory for warp travel. Word bearer ships outright don't use them. They use runes and glyphs to hide themselves from the vast majority of daemons, then just put up with the rest of them. With as few of us as there would be, we wouldn't have much presence within the warp to hide, anyway. Yes, we might get attacked by a couple random, smaller daemons, but we'd be able to fight them off much easier than the couple hundred or so people that occupy the bridge of an Imperial Navy ship.

And, actually, we've got a good deal of time. We'd be a single, fighter-sized ship amidst a battle-fleet gothic sized fight. Once we get out of the ship with the giant "Eldar come get us!" sign on it, we'd have plenty of time.

Also, I Just pointed out that we've not yet seen him attacked. It's not my fault that the space marines are more interested than fighting each other than the ork. Honestly, as soon as we learned we were in a null-zone, I expected a bolt shell in the head. Especially after he, ya know, passed out after attacking someone.
