"The Ruby Rod of Asmodeus is the most prized divine artifact from all of the Nine Hells of Baator. The Ruby Rod of Asmodeus is a gargantuan Magic Rod with the body shaft made out of a black obsidian like metal and the top having a large Red Ruby held in place by a Platinum formation . The Ruby Rod of Asmodeus is the container of the power of the actual original Pact Primeval signed by Asmodeus and the respective gods. Also it maintains the order of the Nine Hells as they are. The temperature, the climate, the physical formations, hierarchies, structures and all the soul magic within the Hells is maintained by the Rod.

The Ruby Rod is the key to Soul magic; it is the key of the extraction of power from the souls of Mortals. The Ruby Rod is the source of The entirety of the Hells. Nothing in the Nine Hells of Baator would remain without the Ruby Rod. Given enough time if the Ruby Rod is removed from the Hells, then the lesser devils would begin to die within a few months and within centuries all of the residents of the Nine Hells, except for Asmodeus himself would perish (Asmodeus does not depend on soul magic, since he is a True God).

Since the Ruby Rod was formed in the Nine Hells, it is a considered infernal in nature not divine. Therefore, it can pass through the divine gate and reach Exandria. No mere ordinary mortal is powerful enough to even stand the presence of the Ruby Rod, let alone come into contact with it. From the eyes of a mortal within Exandria, the Ruby Rod would appear like a large black chained fallen over cylindrical tube with the ruby appearing as a gigantic mountain sized red colored stone."
