Graxos III is a neighboring planet of Graxos IV, home to a Green Lantern legacy family. Unlike the people of Graxos IV, the people of Graxos III are a barbaric race. Future Sinestro Corps member Karu-Sil lived in the jungle after her parents were killed in a raid on their home. She was befriended and raised by a pack of wild beasts before Green Lantern Blish, uncle to future Lantern Arisia, killed them, thinking the little girl was in danger.
