The ancient ones who once roamed this land crafted this strange porcelain obelisk with its ever-flowing waters. Many millennia have passed since they left this planet, but their strange enormous objects remain.

Our engineers have worked out how to use this obelisk as a power source, its waters turning turbines.
Our archaeologists have unearthed a circular object, inexplicably buried deep beneath the ground.
Visit this holy land and... ride go karts for some reason? (I built the go karts before I thought about a theme)

Thanks to Ulvenwood for letting me inherit his plot and adapt the toilet and small boat he left for me.
