The Great Cleft Island of Arachna is a large land mass west of Silesia and the Island of Garlan. Arachna is the convergence point for all the great cracks on the face of the planet and, at its heart is a great and constant tornado. The land is largely tropical rainforest on the western side of the island with desert and mountainous areas to the south. There are many strage creatures inhabiting the land, however, the only known people on the island are the beast men of Nanan.
