Telfenham's experienced eyes knew as soon as they landed on the deep crater in the ground that they had found the way to Maladomini. It would require skill to make it to the bottom without flight. At times, the going was so treacherous that they had to lean against the wall, their toes hanging over what little portion of ledge there was.
At last, they reached the portal and peered through. The deepest chasm in all Malbolge deposited them at the highest part of Maladomini - an incredibly tall and straight spire in the city of Malagard. Far below, demons worked inexhorably to create the straightest and most perfect city for their Lord, Baalzebul. As far as the horizon reached, were the ruins of cities past - all built then abandoned for their lack of perfection.
Here the trio could fly undetected and the space between the demon spawn and Velentham seemed to clear his mind by a fraction. Telfenham breathed an inward sigh of relief - he could focus a little more on the task at hand. Mythology had informed him that one of the abandoned cities held a sewer system so flawlessly designed that it was the envy of every sewer system in the planar realms - save one part that dipped too far down. That single part was what they needed to reach the Plane of Cania, the eighth level of hell.
The small but impecably built city was far from abandoned and only fortune kept the band from being discovered by passing fiends. The sewer system literally crawled with blobs, algae demons, weresnakes and rats. Telfenham knew deep in his soul that Velentham was reaching the breaking point, but there was nothing that could be done. They could not turn back, they could not stop. There was nothing he could do but guide and hope that fortune kept her vigilant eye upon them.
