Ilijah

 was a lizard species used by the Boor to extort money.

Biology
The were black lizards that fed on humanoids and killed them when they hatched from them. They came from a planet just of animals and were genetically re-engineered to become more violent but this reduced their lifespan. They could fertilise their own eggs and squirted them at victims which would host them. When hatched they would rip their way out of the hosts body, normally through the neck. The Boor induced a weakness in them which would make them susceptible to a chemical. (PROSE: The Gods of the Underworld)

History
The Boor used them to extort money from peoples they wanted to scam. They would place them on a planet and wait until the peoples begged for help and would sell the serum at an extortionate price. They were later deployed by the Nishtubi in order to get the Boor out of suspended animation (PROSE: ''The Gods of the Underworld
