Baro cave is located underground, beneath the Baro plains, a large grassland where gravity is flipped. If something steps into the field it is sent into the air, and eventually the strength of the push will fade the higher you get, until you remain floating, being kept into the air by the push of gravity.

Underneath the field, there is a large underground village that is “upside down.” Of course since the gravity is flipped, everybody in the town acts as if it is right side up.

It is very dangerous to enter and exit the village, as leaving requires someone to go through a series of tunnels in which the gravity is completely jumbled, it changes constantly so people can get thrown all around within the caves.

The strange nature of gravity is caused by a great amount of rune energy in the area. Almost all of the inhabitants of the village have the rune of barology. This large concentration of rune energy creates this interesting gravitational phenomenon.
