Battlemap for the d&d one-shot, The Lich Queen's Begotten. This features the Port District in Tu'Narath, capitol of the Githyanki. It features several levels, the port which has Astral ships and warehouses, and a floating citadel high above that serves as a watchtower and HQ of sorts, patrols are sent out from it.

The bottom level, "Port - Bottom Deck/Ground Level" has details for each ship type if you click on them, and the general map itself in the GM Notes in the bottom right of the sidebar. I changed the ship size slightly compared to M's Tome of Foes, the notes also includes standard crew & guard size. The citadel is 100ft above the port and does not have gravity, going by the Astral Plane rules for movement. Each floor of the citadel has notes on its purpose.

The entire area is supposed to be slightly foggy, I couldn't figure out how to add it to the map in a way I liked. You can describe it that way, I use the Fantasy Grounds app to run my games and figured out how to add the fog there.
