As the war between the Fourth Kaiantoran Empire and its enemies dragged on and approached its end, Windjammer Isle eventually found itself the sole territorial possession of the rat armies other than Kaiantor itself- and the armies of Asckon and Kazarheim were advancing swiftly upon the little island. Slygvorn rallied the rat lords and their fleets and met the enemy armies at Windjammer Isle.

After a battle that lasted two days, Slygvorn was finally slain and the rat armies routed and massacred. The Fourth Kaiantoran Empire came to an end.
