[Spoilers] What are treasures used for +other stuff

[PSY]

After killing the endboss, Mount Grimrock starts to break apart. There's lava all over the mountain, and explosions at the top.
But there's also some kind of lightning storm, and a gigantic beam.

If there just had been a gigantic explosion, you'd see some rubble, boulders and fragments nearby. But there's nothing. Just a badass hole ^^
