The fortress is divided in three parts: * The first part is the entrance to his battle cruiser * The second part is the main part of the ship, battling against his troops and Spider Walkers Guardians * The third part is a stretch corridor than you must escape to battle Klaus. After this Klaus shows his own version of the Flintlock, this is your final boss. In the ending, the Flintlock sends the Flint back through the atmosphere of the planet, where it morphs into a naked fairy for some reason, and saves planet E-Square.
