Hi Mac,

It's entirely possible to expand the map out further beyond its current limits. This is just a sectional snapshot of a piece of it that relates to the adventure. I got to see Havard's Jackport map, nicely done. There could be multiple levels of sewers, cisterns, and catacombs running under the city. My suggestion is to utilize the random dungeon tables found in either the 1E or 5E DMG to make some sprawling underground locations for your players to get lost in. The ladder in this map could be 2, 3, or even 4 "levels" below the surface (perhaps Jackport's sewers are to the Blackmoor campaign world as Waterdeep's Undermountain is to FG).
