Oooo... Time magic? Ferrin is veeeeeery interested in time magic.

I suppose that will be a reason why Ferrin would talk to Grane and probably join him when he teleports underground. But Unlike Time Lord, Grane can only effect non living things his time magic, which might be a bummer for Ferrin. Grane might be strong and has a large collection of magic that he can use, but because he knows so much he only prioritizes on mastering a few than all. Arc of time would be one that he's still trying to learn.
