WE FREAKIN' KNOW WHAT HAPPENS WHEN WE PICK UP THE CRYSTALS!

Radium sez to try what we know. Here is what we know:

-The crystal in the inventory is important (A piece of the puzzle?)
-the crystals can be rotated, but not moved from it's place, and not lifted
-there are four crystals divided in two rooms, and 7 in the other two, making 11 in the four rooms all together. 12 if you count the one in our inventory
-there is some significance to the poem that is written on the wall. A possible breakdown of it
-Sombody else was trying to solve this puzzle before somthing got him.

Could fooruman or someone else fix the PDA? it might hold a clue.
