Umbra Gradum

Curtis’ semblance, Umbra Gradum meaning shadowstep let’s Curtis seemingly teleport short distances instantly; while evoking a “black mist” around himself as he vanishes and reappears. It is unknown exactly what causes this “black mist” and exactly how the semblance manages to seemingly instantly transport him from one spot to another.

Even Curtis himself doesn’t fully understand how the semblance works, he just knows exactly how to operate it, since he has been able to use his semblance since birth. This semblance is one of the few known hereditary semblances which have been passed down through genes from father to son, mother to daughter; although it is not definitive that the semblance will awaken for each generation.
