The map above was found in The Archives belonging to the House Strakarson. Most likely it was drawn by some adventurer. File is partly corrupted and no date was assigned to it, thus it's impossible to determine map's age.

HERE you can find the reason why the map is so primitive and lacks almost any names. In fact, it may be the most detailed map of the planet ever created (or rather ever shared with anyone)!
