What should have been a simple day for Jesse and his friends at the Endercon competition turns into an adventure full of peril after Ivor unleashes a monster named the Witherstorm, a powerful monster that is able to destroy everything in it's sight.
After surviving the horrible destruction that the Witherstorm caused, the crew must go to Redstonia and Boom Town, to get the rest of the missing pieces of the Order Of The Stone, Magnus and Ellegard. Although, the crew will only realize that the Witherstorm has only just begun and that danger is only showing it's seed.
The crew has realized that the Witherstorm is only getting stronger and more unstoppable. The only way to stop it is by having the one and only person stronger than Gabriel, Ellegard and Magnus. Soren. However, to get him, they'll have to go deeper than ever before.
Just when peace seemed to set in, the crew realizes that their plan has had a flaw that only made the situation worse. The crew is now hopeless and can't find any ideas. However, a shimmering and extremely tiny hope hides. The problem... it is very far and dangerous.
On a tip from Ivor, Jesse and friends head to an abandoned temple holding mysterious treasures. Ambushed by former Ocelot, Aiden and his crew, our heroes find themselves in an entirely new world: Sky City.
Continuing their portal journey in search of home, Jesse and his crew land in a world entirely controlled by PAMA - a sinister "thinking machine" determined to command everyone and everything with redstone mind control chips.
Having survived supernatural storms, maniacs in mansions, malevolent intelligence, and more, Jesse's crew have one last and potentially lethal trial before they can find their way back through the Portal Corridor.
