Refinery

The Refinery is a specialized science building exclusive to the Folktails faction, requiring 400 Science Points to unlock. It employs 1 worker and produces two important late-game materials: Biofuel and Catalyst. These products serve critical roles in the Folktails' advanced technology tree, with Biofuel functioning as a freely accessible energy resource (similar to how beavers access water for thirst) and Catalyst enabling various advanced crafting recipes and processes throughout the colony.

Biofuel produced at the Refinery is stored in Tanks and distributed throughout the colony for use by bots and other consumers. The Refinery's production chain requires input materials from your colony's agricultural and processing infrastructure, so a mature supply chain is necessary before the building becomes productive. Players should plan their resource pipelines carefully, ensuring that farms, processors, and transport routes can keep the Refinery supplied without starving other essential production lines.

The Refinery represents a key milestone in the Folktails' progression toward late-game capabilities. Its products enable the faction's unique approach to bot support and advanced manufacturing, distinguishing the Folktails' tech path from the Iron Teeth's more mechanized approach using Charging Stations and Control Towers. Building multiple Refineries ensures a steady supply of both Biofuel and Catalyst, which become increasingly important as the colony scales up its bot workforce and pushes toward endgame projects like the Earth Recultivator Wonder.
