Salt Coast: The Ancient Mist
One of the eldest gods, the Ancient Mist covered the world before the sun was born. A primordial force, the Ancient Mist has few adherents in the mortal realm outside the elven family of shadow, but mortal fear and elven memory fed it and keep it strong.
Dwarves abhor the merest mention of the Mist and will make the sign of the evil eye if it is mentioned in their presence.
