Acolytes spread the gifts of Xeen to the masses. They may do this as junior positions within temples or as wandering priests and priestesses. Acolytes may choose to split their time within the temple and travel, but all are expected to perform to the expectation of their superiors. Trials for passage to the Lower Chambers are designed and carried out by Ones in the Sky and usually occur in conjunction with a Night of Flesh and Magic. Trials passed, the acolyte continues as a devotee in their path.
To fully answer that you'll have to wait for the pantheon document. However is NOT like the one previously described as the assention and origin of Xeen are completetly independent of Lucinda and Corath.
How do you rp when there are changes like this?
So xeen is no longer the child of Lucy and Cory Knucklehead? :p
