Major Characters in Location Neido , Brannan Landers , Bronson Jarls
Main Location of Nexus Tower
Enemies Stromling Invaders

Crux Prime is the world on which the Nexus Tower is situated. It is still a scene of heavy fighting between the Maelstrom and the Nexus Force. It is a jagged landscape patrolled by the most powerful Maelstrom monsters, which can be known as Stromling Invaders, or just the Invaders. This world was released on February 8th, 2011.


After completing missions for Duke Exeter, players are able to fly to Crux Prime via a Teleporter in Nexus Tower and talk to Brannan Landers. Brannan is attempting to control the fight on Crux Prime, however he is worried about a pilot named Sherland Powers, who flew too close to the Maelstrom cloud surrounding the planet, and went down.

Brannan sends them to find Sherland, who is pinned down under a Shield Generator in Rivendark Canyon. Sherland partly mistakes them for being in poor shape, and tells them to smash Koi Wreckage to help survive. He then sends them on several missions revolving around his revenge for the nemies on Crux Prime, and completing the missions he failed to do by crashing.

If players return to Sentinel Point Zeta, they will learn that Brannan once again has his hands full, both with a shield generator issue and with curiosity of a mysterious Ninja, who saved him from even more so mysterious Skeletons. He sends them on two different missions, to repair a shield, and to find the ninja who saved him.

When players find the Ninja, named Neido, they are once again flung into adventure to find the source of a skeleton infestation on the edge of Crux Prime.

Throughout the gameplay of Crux Prime, players will learn and uncover more and more about the history of both the Maelstrom, and the Nexus Force itself.

New ItemsEdit

Crux Prime was released in February with the promise that more Ninjago content was on the way. However, at the time, players were given the use of a Spinjitzu Staff from Sensei Wu. After the Ninjago Update, the staff was changed to a dagger once Wu abandoned Crux Prime to Neido.

Additional gear sets released at the time were the Skeleton Suit, and the Mosaic Jester. Two other sets of gear were based off of classic LEGO characters: "Batlord" from the 1997 Fright Knights theme, and "Explorien Bot" from the 1996 Exploriens theme. These marked the first four Non-Faction Specialty kits, including Sensei Wu and Neido's spinjitzu suit kit.



Crux Prime is home to the Skeleton Dragon Pet after the inccident which landed the Ninjago Monastery Ruins on Crux Prime.

The Pet originated in the Ninjago Underworld, however when Sensei Wu flew the Ruins into Crux Prime, it was brought along, unknown to him. Players were able to tame the beast after completing a mission chain, however when Wu returned to the Ninjago Monastery, he did not leave the knowledge with Neido, who was forced to find out for himself.

The Dragon can be tamed after completing several missions for Neido.

  • The world's original name was Aura Mar, but was changed before the official announcement. Aura Mar instead became the name of one of the world's locations.
  • Some early concept art shows that Crux Prime may have originally been intended to be an icy, arctic battlefield. Other pieces of concept art show that mechs may have fought alongside minifigures.
  • Crux in Latin can mean several different things, including "cross" and "torment".
  • Crux Prime contains more enemies than any other world to date.
