Overview
Captain Mark is a magic that contains hidden arcane knowledge and magic from across the world introduced by Sinbad. While it is unknown where it originated, Sinbad said magics is written in them, and when the user is given one, they be able to use one of the magic in it. The Mark chooses the magc depending on the user's main magical power. For example, James Cook mainly uses Navy Magic, a combination of Water and Heat Magic and so he would have a magic on those two magics.
