The Blood Collector
This artifact of legend has been crafted by the new gods, after the bloodtheft has been discovered and The Gorgon started to breed bloodlines to empower himself. The Blood Collector has been lost for years, and his last owner is unknown.
Omer had a revelation from her goddess, Avani (see Religion), and raised an adventuring party to recover it.
The Blood Collector is a magical chalice that allows up to 7 drinkers to share the blood of a slew awnshegh. The drinkers must have different derivations in order to drink from the chalice. The bloodline strength is then shared between the drinkers, which are bound by a magical oath of assistance. According to the fact that the Blood Collector can fall into the hands of good-aligned characters, this would be a powerful weapon to fight the forces of Evil, and even, maybe, face The Gorgon himself, although this is unlikely :)...
The quest for the Blood Collector will cause a lot of antagonist to face the PCs, and only their unity will keep them alive...
