Oun-mAa Niye Ressoot (Location)
A First Civilization tomb. It shows up on the map with a cave entrance, but this is a dead end- you need to enter through the Golden Tomb.
Pass through the cobwebbed door in the ancient tablet room to proceed.
The passage will allow you to open a crack back to the outside world. Slide away the rack, but don't leave yet.
Slide down passage, into the pillar room.
Gather the silica from around the room (and ponder the inordinate number of chariots), then activate the pillar.
This completes the location.
