I'm working on an Aurilandur heresy, which essential is a heresy based pre-corruption Auril, for a 3.5 game. However, I came across a mentioning of a more benign variant of Auril-worship in Sossrim in RoF. Does anyone know anything more about it, or am I more "free" to work it how I want?
TSR9545 "Prayers from the Faithful" p.86 makes reference to Alaphaer, as an old name for the goddess Auril. My opinion is that Alaphaer is the human name for this benign aspect of Auril. Aurilandur, "the Frost Sprite Queen" would be a name only commonly known among the fey.
On a related note: I named a river in the Frozen Forest the 'Alaphaer Run' in the adventure Monument of the Ancients [Dungeon magazine #170]. You can see it in the map of the Moonsea North on page 56.
