Titan Trove / Jewel Mines

When you kill a titan, they spawn. They aren't random, and you need to research to gather them.


(This is true as of today. I can't say what will be true in 2 days, lol.
Titans may or may not be the only way for gem/jewel nodes to spawn then, but if/when another way comes about...it also won't be random...there'll be a reason that it spawned, and those who caused the spawn will know about it...)
