"The Siloc are the Mermon from the Silent Ocean. They are hard to recognize as Mermon because of their radically different appearance. With sharp bone protrusions from multiple points of their bodies, nerve strands that are thick like dreadlocks, and skin where eyes should be, some mistake them from a monster that have crawled from the deep."
