Looking for maps for a Djinn's fortress

Looking inspiration for a Homebrew rescue mission from the claws of a Djinni's collection. as the space should be extraplanar, it could be a cave, desert fortress or tower... could anyone direct me towards some fun maps?

It just so happens to be I just released a short adventure that is centered around just that! (loosely) <a href="https://marketplace.roll20.net/browse/gameaddon/12336/talshari-oasis-adventures-in-the-sakhelim-desert" rel="nofollow">https://marketplace.roll20.net/browse/gameaddon/12336/talshari-oasis-adventures-in-the-sakhelim-desert</a> ^This is a short adventure (about 20 hours worth of content) that has a lot of reference to an Efreeti, though it is a long abandoned temple. There are a lot of tokens made by Jan Loos in this set, and tons of desert maps, including an Oasis outpost, a Kobold/Basalisk Cave, and an Efreeti's lost temple.&nbsp; Also I made the maps stand alone available without the adventure (and tokens) in case anyone just wanted the maps and not the adventure that comes with it: <a href="https://marketplace.roll20.net/browse/set/12335/map-pack-desert-encounters" rel="nofollow">https://marketplace.roll20.net/browse/set/12335/map-pack-desert-encounters</a>
