How about a Muse of Time?

Oof. See, Muses and Lords are the ones I like talking about the least because with the range of their powers, it’s hard to say what they CAN’T do. I could, however, imagine the Muse of Time being some sort of Time Keeper, altering the flow of Time at their will, going back and forth and switching Timelines however they pleased, a weaver of fate of sorts, if that makes sense.
