Definitely helps to know for certain, Malixe.
I'm pondering the idea of a Dawn caste in CBA if I could get CBA to work as a spacesuit. The Solar version already has wings and an hour's worth of air, so that doesn't seem to be a stretch at all. The tricky part would be that you apparently can't get Manses, so no clue how that part would work.
Warstrider could get even more awesome in a mecha-in-space kind of way if I went that route. That'd require assumed methods of environmental seals and booster jets to control direction, though.
Although, without manses, how would you work these kinds of things? Is there a battery or something that Alchemicals can use? I'm guessing these Essence Capacitor things? Never did learn Alchemicals...
