Mardolf the Orange, also known as Mardolf the Inventor, is an Assembly Wizard found in Brick Annex just outside Assembly HQ. As part of the process of joining a Nexus Force faction, Nexus Jay sends players to Mardolf the Orange to seek Assembly's Faction Approval. Seeing great potential in players, Mardolf the Orange gives players a part of the Nimbus Rocket and tells them to incorporate the rocket piece in a new rocket. When players accomplish this task, Mardolf the Orange presents players with the Assembly Badge to show that Assembly approves the players' induction into a faction.
