I have a few questions; 

1. To what extent is magic in existence and usable by humanity?

2. Are those Makitherin weapons supposed to be more like the swords from Game of Thrones where they're just better quality and reknowned, or do they have magical properties and capabilities? Furthermore, would I be allowed to have mine somehow be a specialized warship, or at the very least superior armament upon one?

3. How advanced is naval technology during this time period, are we looking at later middle ages with Carracks and such in existence?
