Spawned from the corrupted influence of adventurer Guy the Grateful during his torment under the Crimson Hands watch, the Fell blade was an immensely powerful ruinous sword with the ability to utilize Rift Magic. In certain circumstances of dire need, the blade was even known to be able to tear interplanar rifts at its wielders will, eventually saving Guy the Grateful from Erwin in the events of the Battle of the Four Armies.
