Xenition Power Stones

Each is more powerful as the others are collected

The stones were developed by separate gods to imbue a hero with their powers, so that the hero could do their bidding without the god's risking death on the material realm. The hero battled against the most powerful demons single handedly and played a significant role in sealing them into the Abyss.

During The Titanomachy, a great hero named Xenith had the audacity to approach many of the gods individually. He proved his worth before each of them and in return was granted a piece of their power in the form of 6 stones. While each stone individually has incredible power, when they are in near vicinity of eachother, it is said Xenith had the power of a god himself.

Xenith fell at the end of the war, and his followers fought for control over the stones. They ended up being split from each other as control was divided through civil war. The gods, having agreed never to interfere in the material world of man too heavily again, used their small influence to lock the stones away.

Legend became myth, and nobody has seen a Xenitian power stone since.
