Game Summary

Rhiannon: Curse of the Four Branches is set on the Celtic fringes of Britain; a place where myth and magic spill into reality, threatening the sanity of a teenage girl named Rhiannon Sullivan. An ancient battle for revenge engulfs Ty Pryderi, the remote Welsh farmstead Rhiannon now calls home. She begins to hear unexplained noises, see disturbing visions, and experience other chilling paranormal phenomena. There is an ancient evil lurking in the walls of Ty Pryderi that holds a terrible connection to a timeless struggle between man and magic fabled in the Mabinogion Legends. Her parents take Rhiannon away, leaving Ty Pryderi to your watch and exploration, but their absence can only postpone the inevitability of revenge and death. Unless you can stop it!
