I was amased whan i saw the announcement today!.
if was thinking why The Larians would choose for a name as Riftrunner (R3).

then i saw on the official R3 site a picture of a deadknight and the hero with a staff?

and this is my theory:
Like the name sais it's riftruner.
i think this game you have to cross in differend timelines.
look at the clothing of our hero.
he has a t-shirt with a lightning symbol on it.
that's soemthing from our time!
so i thingk the "rift" is a gate in time running back and forward.

that would be interesting...
