At the old airship core factory

Expedition

The party found the old airship core factory on the outskirts of the Old Capital. They realized that there is no fully functioning airship core inside the factory. So they have to assemble a new one. This requires a lot of steps. The party encounters a tribe of Magmi, and through clever ruse evict them out of their village. Later the party encounters a sealed control room where they find several dead factory workers. Meanwhile one of their own is up to nefarious plans. And no one would learn anything about it if not for Cullen who just happen to be near "Cade". Cullen overhears plans for demise of the party and tries to warn them. Which prompts Cade to reveal his true form of a demoness K'hagarin. They defeat the demoness and find all the possessions of their friend Cade and a mummified small right hand.
  After a long rest the remaining members of the party and Cullen continue creating the airship core and stumble upon a giant locked door that can only be opened from the other side. Since the whole factory is burried underground this door has to be another entrance from outside. There a hydra has made her lair. After defeating the hydra the party discovered an ancient temple dedicated to the four floating islands.
With the path now cleared the party finished the airship core. And returned back to Mos Eisley
