I'm pretty sure the gem rooms work like this: if a gem is picked up or taken out of the room, the POV gets impaled.

If the tiny shard in the corner is picked up, the eight spikes come down and block the exit, and picking up a gem will not impale anyone. However, all the gems must be on the floor and the shard must be put down before the spikes go back up.

If L33tz4n is standing by the doorway, she gets impaled.


So let's not pick up the gems. Something tells me that we need to figure out the poem and the carving before we can make much headway on this puzzle.
