“Cookie-generator” – is a popular slang term for energy crystals created to control the bio-rhythms of plants primarily used in agriculture.
Properly tuned, when these crystals are aimed at “patrolling” fields they make it possible to generate several hundred harvests a year, instead of the standard one or two. They can operate in either industrial mode for large farms or individual voice setting mode when used for personal purposes.
A known bug: if incorrectly tuned, crystals can give birth to real monsters. With this in mind, and taking into account their natural inattention, the Salangans always equipped their plantations with napalm flame guns to eliminate “incorrectly grown and aggressive products”.
