Siege of Yosai

The Finale of The War of Worlds arc, and the conclusion of the Phoenix storyline. A massive sprawling fortress nestled at the site of what was once the human capital of Neo Pangea, Yosai is composed of several sectors, each must be cleared in order to advance to another sector farther in. Flying is impossible unless allied with the fortress, as powerful ancient magics and the wills of four mighty Lambda Lords govern the space as though their own personal domains.

Ruins
The outer limits of the human capital, the survivors are persecuted and are treated like animals to be herded and experimented on for the sake of progressing Chaos Engine evolution. This area is protected by the Lambdas born under the Phoenix Empire and allegant to their cause. Staging ground for the true invasion.

Green Sector
This area is the second major expansion of the Fortress since its landing, a vast mystical garden full of nature and mythical creatures, as well as the Court of Gurin. Humans brought to Gurin are subjected to her desires and warped into entirely new beings, or transformed into children of Nature, with some becoming her very own Lambdas. The easiest sector controlled by the Four Lambda Lords, but only in comparison to the strength of those further ahead. Indeed, powerful, mystical monsters roam this sector and in order to proceed, one must face and defeat the Lambda of Creation, Gurin herself. Even the plantlife and terrain itself will seek to ensnare and destroy.

Red Sector
The first expansion after landing, it is the complete opposite of the seemingly serene landscape of Gurin's Sector, and is a hellish landscape with twisted angelic architecture, fiendish creatures of unspeakable cruelty and malice, and in addition to some of the most powerful warriors dwelling here, are home to volcanic landscapes, bottomless pits, and tall, vast buttresses that stand against any would be intruders. Worst of all, the Lambda of Chaos rules here, inflecting madness and punishment to traitors, turning innocent men and women into the newest breeds of Chaos Engine to fuel the war effort, and directing the military campaign across Neo Pangea. In order to stop the advance of the Chaos Engines, this sector must be conquered. But to do that, one must face the legions of warriors and demons, the nefarious traps and twisting corridors, and finally, defeat the Lambda of Chaos herself, Abeni.

The Grand White City
The center of Chaos Engine society, the two heads of power, Gina and Azula stand vigilant for those who think themselves capable of defeating their legions. Grand towers rise high into the sky, while deep vast dungeons and labs stretch deep down into the ground, a place where the darkest and most cruel of experiments are performed on subjects, and where capital punishment is rendered to the highest offending criminals. The most powerful of minions, monsters, and warriors defend this sector, and it must be taken to reach the Keep, and stop the two leaders of Phoenix forever. If not, the superweapon, the Spear of God may be used in a final attack on the enemies of Phoenix.
