“Not dark but beautiful and terrible as the Morn! Treacherous as the Seas! Stronger than the foundations of the Earth! All shall love me and despair!”
According to the Elves, there was a time when the Greater Fey did walk alongside the Undying Elves. Then came the Sundering, unkindly ripping the Dreaming apart. Lesser Fey still managed to exist across Aerth, but the Greater ones retreated across the Sunder where they still dwell to this day.
Thus did the Courts of the Fey split into the Seelie and Unseelie. King Oberon and Queen Titiana formed the Summer Court known as the Seelie, joined by those who shared an ethos of beauty and life. Others who embraced the ideals of personal might over that of honor followed the dread Queen of Air and Darkness. Do not depend on the Seelie to be kind or helpful for they have their own inhuman agendas to follow, nor are all Unseelie malevolent or evil. In any case, these are beings of terrifying might, not to be trifled with lightly.
The Fey keep no clerics. They do not seek worship but are beings to be appeased and bargained with, most commonly by warlocks and the like. The Greater Fey are known by many names for a True Name would carry far too much power. To invoke the name of a Greater Fey is an invitation to risk.
