The bloodel replaced its ancestor sublyme disease. Like its ancestor it gets passed around when the carpozoa gusherwurm feeds on red blooded carpozoa species. Its has evolved a proboscis so it can better feed on the blood cells of its host. The host once infected has trouble stopping bleeding thanks to an anticoagulant it produces. This attracts more gusherworms to feed and thus can be passed on to a new host. It is fatal in most victims however not after a lengthy suffering of bleeding to death.
