Old God

The Old Gods are, according to background information presented in the Lords of Shadow series, a group of powerful supernatural beings who were once worshipped by humanity before worship of the One God became prevalent.

History
Not much is known of the nature of the Old Gods and the manner of influence they wielded over mankind. By the beginning of the Lords of Shadow series, whatever power they held over humans has since dwindled. Nevertheless, in the more remote and inhospitable regions of the world, their influence is apparently still very much active among the world's non-human inhabitants and assorted pagan societies.

Most of the Old Gods are regarded with dread by most humans and considered dangerous to others, most especially the Brotherhood of Light, although some, such as Pan, are more of a neutral force than others and even provide assistance to humans on occassion.

Pan - An ancient anthropomorphic ram who resides in an isolated glade in an unspecified forest. He plays an active role in the affairs of the Brotherhood, and played a major role in Gabriel's conflict with the Lords of Shadow, sacrificing himself so that he may reach the land of the Necromancers.

Leviathan - Identified as an Old God though never seen nor fought against. His existence has only been hinted at by the presence of his spawn inhabiting the lowest floors and waterways of the Bernhard castle. Furthermore, it is speculated that he is impossibly large and
