The Kah'Rul are an industrial consumption race who conquer planets, industrialize to their liking, terraform to their preference, and turn the planet into another resource node in their increasing pool. There was a time when they would consume and conquer at a rapid pace as told through stories told by their slave cultures.
Slave cultures are held in the lower decks of Kah'Rul ships in massive containers where they can be easily contained and deployed. These cultures live as if they were villagers in cargo rigs so large, they poses their own eco system, constantly forced to travel and given nothing more than what they need and are usually only used for manual labor with a select few loyalists given more critical responsibilities. The Kah'Rul only lightly reward loyalty, augmenting and indoctrinating their captives in order to ensure control before granting higher responsibilities and comfortable living quarters for their families. Even when given better living situations, the families of their peace keepers are kept at the end of a barrel to keep the "officers" in check.
Kah'Rul are incredibly large, generating a great deal of body heat. This is normally countered by the climate of their frigid home world, Arkhas. Any planet they take, they often terraform to cool into a wintery state. Due to their size however, they can carry greater-powered type of equipment; making their weaponry and armor far more powerful than most, basically walking tanks.
Kah'Rul
Primes are full grown, all natural with no genetic modification. On their own, they stand roughly a staggering 14ft tall with huge spikes coming from their spine and back, thick reptilian skin and they hunch their back forward by their natural posture, making them look sometimes a little shorter. They are extremely resilient to most conditions except extreme heat, preferring cooled environments.
Det'Ril
The sub-race of Kah'Rul, genetically modified to be more surgical and akin to other bipedal opponents, bred to fight on the home planets of other, smaller races. They are typically 7ft 6in to match the life forms of most the worlds they invade, giving them a surgical advantage over their Kah'Rul
