Yea, so I talked it over, and we're thinking a warship would be too much as a weapon preference. Stick with standard Medieval weapons, although you can improvise a tad in that regard.
He could have had a warship sometime in his past, if the situation permits it (in his History meaning), but no, he can't have it as a weapon in the RP. That might be pushing it too much, I think.
Aye-Yo, Supervegeta, for Hyrus, can my character be a captain of a war-ship? (Like, he has his own warship, it could count as one of his weapons if that is necessary)
