Warrior-Caste Hatchery Créche P152 was an installation on the planet Sazssgrerrn in the Gorn Hegemony. It was the only créche world of the Hegemony that bred Gorn of the warrior caste. P152 was crewed by members of the technological caste and warriors of the Hegemonic High Command. Early in 2381, the yellow-white primary of Sazssgrerrn's system incinerated the planet's surface, annihilating the créche. Only about a dozen Gorn officers survived but suffered severe radiation damage. (TTN novel: Seize the Fire)
