A team formed twenty years ago to investigate Makya's mysterious and ancient caves. They invested millions of dollars into infrastructure in southern Makya, and were involved in numerous projects both secret and dangerous. Eight years ago, however, they were suddenly disbanded by the actions of a lone Pokémon trainer. Still, a deal struck between the top brass and the Makyan government allowed most members to avoid jail time. By now, most former Team Chasm members have integrated into Makyan society, but some of the public still refuse to forgive and forget.
