The Amazing World of Elements

I woke up in a room, a very shadowy room. I didn't know what to do except to open the chest that was in front of me.

It contained many things. First thing I saw was a bunch of stones of different colors, and then there was a a bunch of different types of weapons. There was also a mechanical device that I didn't know how to use.

Then I heard a voice in my head. "You may only grab one stone and one type of weapon, and you must take the device."

Once I had done, I that was off.
