You are primarily on the continent of Serilas, which is on the world of Abril. Of course, you have no knowledge of other worlds, and only a few sailors might have any knowledge of other continents.
Here is a map. It includes the continent, the top of the continent below, and the surrounding islands. In format, this is a very big pdf. As in, use your zoom. I am sorry it is sideways, but if you download it you should be able to rotate the view easily.
