It is said in the hidden myths of the banned and hunted Cult of Ma-O, that the Seamus Straits are where Ma-O fell when the god Jove hurled him from heaven. His physical body was smashed into pieces of amethyst and his spirit trapped within the warm waters.

Be assured you will not see this man in the same city twice.
