This is probably the most important sketch I did in those nine years of development. This one sketch was actually enough to convince LEGO that the secret was a good idea. It is a very quick side view sketch of a giant robot (at that point called “Core 2”) lying underneath an island with the mouth under a volcano and a canyon called “Brain Canyon” above its forehead. For many years this was the only visual showing the secret and it was kept in a deep drawer at my desk. We in the team figured that if we were to keep the secret it was a good idea not to make to many pictures of this. We knew that just one “leakage” would ruin many years of good story. We used the phrase “The big story engine” as a code when mentioning the dormant robot.
