The Venture Explorer was a Venture League cargo ship captained by Sky Lane. The Venture Explorer was originally headed to Nimbus Station to deliver modular rocket parts, Minifigure passengers to be recruited into the Nexus Force, and Nexus Data Cards. However, Engine 2 began leaking Imagination, and as a result the ship was detected and attacked by the Maelstrom. Sky Lane sent a distress signal, but the Sentinels stationed at the nearby Avant Gardens were unable to help. Bob, Sky Lane, Jett Moonshot, and the Nexus Astronaut began a mass evacuation of the ship's passengers.
