Whilst testing out a viking-style assault ship to use against the Noops, Urpgor comes across an island that rises from the ocean, he uses the island as a base of attack, and becomes warped by the riches found within it... Urpgor belives he has found the perfect base of operations where noone can touch him, not Rufus, not the Noops, and ESPECIALLY not Zordrack...
