Makrak

The Makraks or Miners are a subterranean race of insectoids that dwell beneath the surface of Thra.

Mostly resembling upright beetles, the Makraks are a semi-sapient race that has adapted to life in the extreme heat of Thra's core. When the Crystal was cracked, its affected the planet, creating a fissure in the crust of Thra and displacing the Makraks from their home, forcing them to the surface of Thra.
