“Cookie-generator” is a general slang term for energy crystals created to control plant biorhythms; primarily for agricultural crops. Properly tuned, this crystal aimed at “patrolling” the fields, made it possible to get several hundred harvests a year, instead of the standard one or two. Can work in industrial mode (used on large farms), and individual voice settings (when using the crystal for personal purposes).
A known bug: incorrectly tuned, gave birth to real monsters. Knowing this and taking into account their natural inattention, the Salangans always equipped their plantations with napalm flame guns to eliminate “incorrectly grown and aggressive products.”
