By the way, what's the status of gunpowder in this rp?

Gunpowder is mainly used in naval battles but some infantryman might use them, much to the distaste of traditional knights. Muskets are not exactly in use, (although a character might invent it) but a precursor, the arquebus or harquebus, is similar. Arquebus' use a matchlock firing mechanism and are not very powerful, only capable of piercing plate armor at very close quarters.

Larger ships cannon are capable of devastating barrages though.
