A ''mythical'' Realm of The Irish ''God of The Sea'' Manannan Mac Lir , ''Emain Ablach'' was said to actually be the Isle of Man. It was believed that it was there that all manner of ''Creature'' lived – many forming the Legends of the many Cryptids and such, found throughout that part of The World. In a later associated Legend (perhaps the 8th Century AD) – Emain Ablach was the mystical Land where the famed ''Excalibur'' (Sword of King Arthur), was ''made''.
