Tenebris

"The blade itself, there was just something off about it. It was as if it had a mind of its own and was speaking to me. Later during a lecture session today, i learnt that the blade was called Tenebris. Apparently, it was a divine artifact recovered from an ancient Aenarri world and it had a mind of its own. It was so deadly to demons that it obliterated lesser demons outright, and if any stronger ones were killed by it, their souls would be shattered."

Tenebris is an ancient, divine weapon that is currently in the possession of the Federation. Found on an Aenarri world, this weapon is known for its incredible lethality to demons and their allies, being able to completely wipe off a demons soul from all of the four realms of time, space, reality and existence. It has been the trademark weapon of Lorann Sanguinus Meros, ever since he has ascended to the position of Second in command of the entire Blood reapers legion

It is a unique weapon and only a few of its kind exist in the universe, another notable one being Bloodrender, which is the trademark weapon of Augustus Ludwig, the leader of the federation and one of the four horsemen of the apocalypse.
