Helios

Helios is the main planet of No Way Out.

History
Helios is a dangerous planet, attempted to be conquered by the PTO multiple times, all failing because of ships mysteriously being destroyed in the atmosphere. All these failings were blamed on things like demons, monsters or magic. Any PTO operatives that survived the atmosphere reported mysterious happenings, most likely because of seclusion, driving the operatives insane. The operatives disappeared, most likely being attacked by the native animals. Then the saiyans landed on it.
