Since many of the necessary structures were already in place, Urok's unit's first task was the collection of resources for the invasion. Farms and slaves were created at a dizzying pace; tankers set out southward to install a platform and collect oil. Their warships stayed close to shore with a zeppelin overhead; their stronghold and towers were upgraded as soon as their supply of resources permitted. Construction continued with a foundry, refinery, and a goblin alchemist to produce more fliers for the invasion. A second shipyard was erected to double their juggernaught production, and soon they had a powerful flotilla in the bay.
