Gather your hatred about you, and master it, my brothers. It is the strength behind your shield, the speed of your blade. Do not abandon it, for without it, you are empty indeed.
The Unyielding Rage
A tiny ampoule of steel and old, clotted blood, hung from a black iron chain, the Amulet of Dark Valor holds the drive of the furies.
For a futuristic grim gory setting. Probably powered by some kind of dilithium battery or something similarly awesome. Anyways, basicly a big drill sticking up from a hilt that you primarily use for skewering enemies painfully and drilling through armor.
