Ptolus: Monte Cook’s City by the Spire is a massive sourcebook for an extensive city. It originally served as Monte Cook’s personal campaign world during the development of D&D 3rd Edition, of which Monte Cook was a senior designer.

Now you can purchase Ptolus for either D&D 5th Edition or the Cypher System. I’m running a Ptolus ‘open table’ using the Cypher System so some of these articles may be more applicable to that system.
