During Groundhog-Fawkes Day, a group of incredibly bored, amateur demolition experts gained access to this abandoned facility. It proved to be a most excellent testing ground for highly-energetic materials.
After the event, a swarm of byte-sized repairmen came and fixed the place up—good as new. Einlund is still accessible via a minecart connection at Ft. Gears. It can also be reached via DTA tunnels, but you will have to stop the cart manually. Leave your TNT at home, please!
