All Creatures in "Khefak"
Khefak Biogenetics bioengineered khefaks to consume scrap thasteron so the waste could be refined into starship fuel. These creatures eventually became a prime example of a solution becoming a problem of its own. After the discovery of Drift travel, Akiton's thasteron market plummeted, removing the need for mining infrastructure, including khefaks. Khefak Biogenetics destroyed the production facilities, thinking they'd completely eradicated their creations. Khefaks are hardy, however, and the few survivors left the facilities. Beyond thasteron, they subsisted on inorganic materials, and their rapid reproduction rate allowed them to quickly spread all over Akiton. Some stowed away on starships, allowing them to spread throughout the Pact Worlds.
