Mani, would the walls technically be older, wouldn't they be the same age? And did you overlap the NP or just replace it?

I figured that they would be older since technically Caster's NP actually sends you to the labryinth of Crete, in a way, while Berserker summons the walls in the present time?

I don't really know, I just kinda wrote it.  :maybe

And I guess I replaced it.  The party sees an empty hallway behind them now.
