Oaha is a Toa that used her creativity in her work. She was an underground miner that used explosives to blow holes in the mines. She was trying to find crystals or anything of value. She blew a hole too close to her and got buried alive. After no one heard her screams, she had to dig a way out using her own armor pieces, resulting in her almost dying. Now she uses one of the crystals from that same cave and protects people that can’t protect themselves.
