Ravine was anti-government rebel and terrorist faction during the Zeboim era. Ravine was openly against Zeboim. When they bombed the Central Power Plant in the Zeboim capital, Kim Kasim's patient died from the loss of power. He was eventually forced to join Ravine in order to keep his nanotechnology research intact. The faction was destroyed by Miang and the nuclear war that destroyed the entire Zeboim civilization and most of the planet's human population at the time. The underground organization Scientia from Xenosaga may be a reference to Ravine.
