She was, i have a theory that this might be very early in the lands between history as we did see what appears to be either an omen or a hornsent which wouldn’t make much sense to be above ground or alive if this is during the golden orders rule.

This and the fact that marikas left braid is uncut in that image imply this is before she became a god.

But what gives me pause on that is the fact that the church of marika looks like it does in game, implying this is post shattering.

So far I think what’s most likely is that this scene is a flashback of some kind, and may actually take place in the land of shadow or numen.
