Jace walked around the room. It was the same sandy stone that decorated the rest of this hidden chamber. But on the roof were four glowing white crystals that lit up the room. They were lighting up the room in the same way that the smaller dark green crystals were lighting up the staircase.
He could feel the energy coming off the crystals and was impressed with how invigorated he felt. Those were not normal crystals and with how much energy was being generated. It could be a suitable power generator to replace radioactive reactors.
On the rest of the roof was another carving. This time it was a bunch of dots and lines with triangles and circles depicted everywhere. The carving went from the roof to the bottom of the walls. With the only thing interrupting it being those large crystals.
