An animal that lives on the Ice Citadel planet. The Silfen hunt these animals for their tusks which they take as trophies. The residents of the Ice Citadel use the rest of the Ice Whales body for various things. These include the meat for food, bones for various equipment and some of the organs have medical uses. The Ice Whales are huge creatures covered in fur – like a polar bear grow to the size of a dinosaur and with a row of arm length tusks curving out from each side of the muzzle. A series of legs run along its underbelly, although these are more like fur-clad fins.
