Heart of Sarnax

When Sarnax sought to purge his soul of all evils, the result was a physical manifestation of crystal that approximated the size and shape of his heart. The evil contained within remained quiescent as long as Sarnax lived, but upon his death, the item gained power, no longer held in check by Sarnax's living soul. If returned to any version of the living Sarnax, this grown evil manifests into a creature made of solid ruby whose first and primary goal is the destruction of its source. Afterward, the Heart of Sarnax can turn its attention to the world, eager to visit upon reality all the evils, both petty and potent, that Sarnax might have pursued had he fallen from grace while alive.
