Immortal Priesthood of Arden

The name of Arden, Elder God of Light, has been all but lost to the collective memory of the world. Once He had a strong and devout following amongst the nations of mankind, and even attracted Elves and Dwarfs to his priesthood, too, but He is considered nowadays to be a Dead God, known for reasons forgotten by history as the Sundered One.
Here and there, pockets of worshippers and lone priests and clerics, often regarded as mad or deluded by those of other faiths, still practice the rites and worship of Arden. Some say there is an organised priesthood still in existence somewhere in Yore, who have attained to immortality through meditation on their God, but this could well be nothing more than empty rumour.
