Once the whole cake has been eaten, NPC Brutus The Baker will appear after the next Server Save. Say help to him, then he will ask you to step on the Cake Base at the island, and then visit the Cake Extraction Machines in Thais, Carlin, Edron, Darashia and Liberty Bay.
Once you have stepped on the extraction machine, return to the Cake Keep Isle, step on the cake base again and then proceed to the next city, repeating the process.
