A DIREWOLF is a close relative of the wolf, but larger and stronger. They are named after the real world direwolves, Pleistocene megafauna, which were larger than modern wolves (but not as large as portrayed in the books). Direwolves are extinct north of the wall, as they are a very large and dangerous predator, and people have probably hunted them out. A grey direwolf in a white field is the sigil of House Stark.
Fury - April, 1945. As the Allies make their final push in the European Theatre, a battle-hardened army sergeant named Wardaddy commands a Sherman tank and her five-man crew on a deadly mission behind enemy lines. Outnumbered and out-gunned, and with a rookie soldier thrust into their platoon, Wardaddy and his men face overwhelming odds in their heroic attempts to strike at the heart of Nazi Germany.
