There is no one here either. At least the place is well lit. After looking around you find a journal. After reading some of it you discover that this research lab was conducting experiments on the glowing stones you've seen. Apparently they've been using it for years but they don't understand what causes the glow.

Random journal entry: "So we had to pull a few strings, but this is the most significant science of our lifetime. Exclusive rights to this cavern gives us a huge opportunity. The glowing mushrooms haven't yielded results, but apparently the petrifyed growth here isn't trees, but some new form of giant fungus. We are running more tests, but if this is the case it opens up the possibility there are live specimens to be found here. A biologically active sample of this new fungi would surely reveal the secrets of the lightstone. Once we can tap into the limitless power of the stone, there's nothing we can't accomplish."

"Intresting, but a live person would be much more helpful right now. I'll scavenge for supplies and follow the road outside. Maybe that leads to the access shaft James mentioned."
