After travelling through the world and discovering the Spider Queen's location, the player destroys the Spider Queen at the Block Yard and claims their first Property, where they could place collected models and bricks. Here, a disaster involving Paradox has infected Avant Gardens with Maelstrom and released a beast called the Spider Queen. The player, aboard the ship, escapes to Avant Gardens with the aid of Sky Lane. The Venture Explorer, a ship carrying new recruits is being attacked by the Maelstrom. The factions worked together to create the Nexus Force in order to destroy the Maelstrom and its minions. After the incident, the explorers decided to form their own factions, Doctor Overbuild creating the Assembly, Duke Exeter forming the Sentinels, Hael Storm leading the Venture League, and the Baron's protégé Vanda Darkflame creating the Paradox. However, even though Doctor Overbuild plugged the hole, the stress caused Crux to explode into thousands of other worlds.

After having found it on the mysterious planet Crux, the greedy tycoon of the expedition, Baron Typhonus, was pulled into the source, fusing with it to create a maelstrom of chaotic dark energy. The premise is that years ago, a team of four minifigures went on a great journey to seek the last essence of pure Imagination: Doctor Overbuild, Duke Exeter, Hael Storm, and Baron Typhonus.
