People say, you can even feel it beating sometimes... Although that is likely just another myth made up by overly impressionable youths.The Ruby Heart is a very potent Place of Power around which the human town of Clerbeliard is built. Kept deep within the castle dungeons, it is used to fuel the town's defenses as well as providing its numerous mages with arcane energy.
The Ruby Heart is probably the most important item possessed by humans west of the Krisna. Its power is the foundation for Clerbeliard's economic and military strength.
