Feri Maris

During th final battle of the gods, The sword of Deermahl carved a great gash into the land and this gash was filled in by the oceans from either side of the continent Adhaesit Terrae. Thus creating the sea of Feri Maris. Due to the magical nature of what happened, the rocks that were thrown into the sky at the time, somehow stayed there and now are used as humongous stepping stones to travel between the North and South parts of the continent over the sea of Feri Maris.
