From publisher blurb:
This Weapon Profile is provided to the Storyteller to expand gameplay and provide further options for same. It may awarded to a Player (along with this PDF) when looting the fallen, or it may be included as part of one of your vendor’s more “secretive” stash.
The Prevail Unbound Core Rulebook is required to play the game.
Some of the background lore for the Weapon is provided, but the nuances of culture and tradition may be further refined by the Storyteller (or the Player in conjunction with the Storyteller). Humanity’s connection to the Spirit Ream is incredibly vast and varied, therefore truths and new pieces of information are constantly being brought to light.
This Horus Magnum was crafted to deliver the Diabolus Round – a powerful burst of dark energy which kills the intended target, or psychologically maims the wielder who overestimated their own ability.
