The party arrives on Regulus and are half-blackmailed into teaming up with a mysterious construct, Slots (Ikks). Their research into the Cog of Regulus, the power source of this great city, is aided by the local Zorigami DU-4. The sad truth is, neither the party nor the island can survive without it. When the party tries to appease them with a duplicate of the Cog, DU-4 and his brethren are forced by protocol to attack. Heavyhearted, the party makes good their escape with the Cog.
