They step into the room

"Let's find out what this place does," Diana remarks, before stepping into the room beyond the plinths.

They slowly slink forward into the chamber, taking care to watch all corners for signs of any more traps, and watching their step for pressure plates of any kind. It is a medium-sized room of 30 to 40 feet, with seemingly nothing in it except a doorway leading into another hall on the other side, and a black gem embedded in the wall above it. The floor and walls of the room are intersected by a gridded pattern, the slits reaching several inches deep, as if a net had carved its way into all the surfaces like a hot knife through butter.

Tyra and Diana slowly make their way across the room, before they hear creaking and writhing from the various sides of the chamber, the sound of bark scraping against stone. Vines burst out of the stonework from all sides through the grids and begin lashing out towards the adventurers, attempting to reach for their limbs and tearing at their garments.

Tyra attempts to parry and batter away the vines but they seem mostly unaffected, and quickly a series of thick vines from the floor and ceiling wrap around her arms and legs and lift her one or two feet into the air, grappling with her as she violently wrestles her arms trying to get free.

Diana takes a more graceful approach, dodging and weaving through the vines and slashing at them as she goes, cutting any that get near her to pieces.
