The One Betwixt, also known as the Interloper or the Thing from the Folds, is a powerful, almost god-like, antagonistic entity from the Great Mist that has been known to introduce chaos into Maradul, though its intentions remain unknown. It is worshiped as a god of entropy by the Tongues of Decay, a cult-like organization that attempts to enact the Interloper's mysterious will. The One Betwixt famously proved the mortality of the Nine Tears by killing the god Calphost.
