This grand chasm could serve as a break between the inner and outer city, separating trade and residential areas, as well as administrative and church districts.
Although Sir Morphy didn't specifically instruct us, we think it would be appropriate to erect a new 'Midnight Tower' in the center of the inner city as a signature building of the Crimson Castle in the later stages of city construction.
Both the inner and outer city have reasonably complete sewer systems that can be used directly. However, in the past, they directly discharged domestic sewage into the Kaderman River. Obviously, this can't be done anymore, so we have to build a sewage treatment and filtering facility outside the city and create a few more water storage areas.
During the recent Ghoul disaster, villains attempted to poison the water supply system under the city! So Lord Morphy issued a special order to separate the underground water source from the everyday water supply.
