The Kronteps are a humanoid barbarian race from the planet of the same name. They believe in military honor and despise the notion of fear, as they will rather welcome death in the battle field than flee from it. At least some members of this species are polytheist and believe in reincarnation.
They appear to be enemies of the Mentors, but the extent of this is unclear, as they do not appear to be a spacefaring civilization themselves. It is possible that they are at the process of being subjugated by the Mentors, or the Mentors simply don't care for them but are known to abduct the occasional Krontep citizen and perform scientific experiments on them.
