The Harbinger

Description
A sword with a nebulous blade, with purple glowing lines marking the blade. V-shaped crossguard, black leather wrapped hilt, and a gem for a pommel, with a glowing purple light emanating from its elsewise nebulous surface.

History
The Harbinger is said once to have belonged to a god of death, and contains the souls of thousands of beings from various realities and timelines.

Powers
The Harbinger has the ability to effortlessly cut through any material and bypass any invulnerability of any level. Any wounds it inflicts will begin to weaken the person they were inflicted upon. If such wounds would be fatal to a human, than the soul of whoever they were made against will be trapped within the sword, regardless of the effect such wounds would normally have on them. Once the soul has been trapped, whoever is holding the sword may communicate with it and any other souls within the blade. Furthermore, the souls will be compelled to speak whatever the wielder commands them to, and can be forced into silence or to answer any questions the wielder may have. As long as the sword is held, the wielder will also be able to speak and comprehend any languages known by the souls trapped within, and if they are proficient in its use, will be able to access their memories. Harbinger is also indestructible, and will alter its size to fit the hand of any who picks it up.
