You inherit your grand guardian’s ranch, in Moon Valley, the first city on the moon.
Collect a bunch of experiences from different periods of time, and group then into chronology that tells the story of how we got to the moon, but also the things that happened along the way.
Draw on diverse experiences from all over, so it tells an interesting story for everyone, and to show how people change a lot over time.
A tower falls into above a mine, crumbling it. This creates Moon Valley… what mysteries await?!
The idea is a large orbital elevator type structure collapses into a mining operation beneath it, creating the initial geography for MV. It also means there are access tunnels spreading out from the valley…
One feature is an illegal dark matter facility, which may have caused the quakes preceding the tower fall.
