The Old God is bound within the failing paths of the Ley Lines.
It is a vessel of a dead god, older than the Empire. His essence was bound long ago, and his worshippers all died off with the rule of the Empire.
The binding kept part of the God in this plane, even though the rest faded to death.
He is trapped by the six epic weapons along the Fairy path.
The Redeemer wishes to gather enough mage power for a conduit tower in order to reach an Imperial god.
