Car Arcanum Jewel Sets?

I just started playing around with the Car-Arcanum mod, and was looking around on the forums here when I saw mention of jewel sets. What's the scoop on that? Can anyone give me a non- to lite-spoilerish hint as to where to start looking?

 

It's been a while but here's what little I remember.

Chris added a couple or three jewel sets that, when complete, give an additional bonus from the god they are named for. These are scattered all across the continent so throughly check out every scene.

You can find one piece of the Geshanna set at the start point of Stringy Pete's Cove.

Sorry I couldn't be of more help.
