The Ilecin Delve
The Ilecin Delve, in the salt flats of The Desert of Raduun, is a vast underground cave system. It presumably holds the Stone Heart, if Naphrem and The Codex of Duri are to be believed, and therefore was a destination of the party after the events at Memphun and the Raid on Desheb.
The opening to the caverns is a massive pit, some several hundred feet across, and holds religious and symbolic relevance for the desert orcs who range throughout Raduun. Referred to as ‘The Great Maw’ or ‘The Mouth of the World’, it is a location commonly used for tribal gatherings and sacrificial offerings to feed the earth and sate its hunger.
