I’ve got a few questions regarding technology. Obviously the setting borrows from Medieval Europe quite a bit, so would it be correct to assume that gunpowder isn’t very advanced/widely used yet? The most you’d likely see is some equivalent of Greek Fire, or perhaps very archaic explosives?

If this is indeed the case, is there some magical alternative to a ship’s typical cannon? Or would naval vessels rely on ramming and hand held weapons, akin to more ancient navies like the Romans?
