As the others speak, Cal looks back behind them. What was once a black expanse is now illuminated by a growing purple light. They are near a back wall of the cave, dotted with tunnel openings in the dark rock. The primary tunnel entrance/exit is a massive circular opening, with many other tunnels leading into it. At the far back of the large tunnel, a mass of writing purple tendrils is approaching with THOOM, THOOM, THOOM.
Phaedra: Side note... Did anyone find anything PURPLE?
Irving: Yeah... LOTS.
Lani: You know... Yeah, that WAS weird, yeah!
Pavel: Just normal stuff, though. Nothing glowy or... god-ly?
Cal stares at whatever is coming down the tunnel.
Phaedra (offscreen): But there WAs a lot.
Cal's eyes pop wide, wide open.
Phaedra (offscreen): And that IS weird.
Cal turns back to them, his eyes locked on the entity.
Phaedra (offscreen): Maybe-
Cal: QUIET.
Phaedra goes silent with a start, and turns to Cal.
