It is revealed that the Command Center is Eureka's true home and is the place where she is to deliver her book of everything she has learned from the humans. It also not only serves as a holder for all the information regarding the Scubs, Coralians, and their experiences with the humans, but to keep the Scub Coral in its dormant state. In episode 47, Diane reveals to Renton that if the Command Center is destroyed, all of the Scub Coral will wake up and trigger the Limit of Questions, which will engulf the entire planet into a large black hole. The only way to prevent this is for all the remaining lifeforms on the planet to merge with the Command Center, that way their mental states will remain alive.
