Dark Ones 50 & 51 (OC's)

Dev L and Dev LI are, for lack of a better word, Devils In Training, more commonly referred to as Dark Ones. They are tasked with learning all the basics and secrets that come with forging demons using the Kingdom of Hell's demon forging book, the Demoncyclopedia. Dev LI (or simply 51) is the newest hell-bound soul to be picked by the Devil to become a Dark One and Dev L (or 50) is in charge of teaching demon forging to them.
