Glory to Ka!
Choose one from the following:
Lantan: March of the Modrons. Forgotten Realms-to-Planescape module anthology. Each module is set in a different outer plane.
Cormyr: They came from Wildspace! Forgotten Realms adventure based in Cormyr. Knights in shining armor versus neogi (alien snake-spiders).
Endgame takes place on a neogi battleship hiding among those asteroids orbiting Toril.
Rock of Bral: Realmspace. Spelljammer anthology with two adventures for each of the other planets in Realmspace (one low-level, the other high-level).
Tyr: Sand and Blood. Dark Sun adventure based in the lands around the Free City of Tyr, specifically the Ringing Mountains and the Great Alluvial Sand Wastes.
Endgame big bad is a powerful noble family from Urik who want to impress King Hamanu by using their personal army to conquer either the town of Kled or Altaruk.
Athasian Chronicles. Dark Sun module anthology based in the Tyr Region.
Final module involves exploring the ruins of Guistenal.
Karameikos: The Forgotten Empire. Mystaran adventure. Think Rise of the Runelords but without all the gross parts, Egyptian-themed monsters instead of giants, and a Nithian mummy lord instead of a Thassilonian archwizard.
Athas: Empire of Chitin. Dark Sun adventure. The J’hol-Kreen have moved into the Tyr Region. Destroy their war machines, drive off their insect monsters, kill their leaders, and save the day. All while disrupting the Sorcerer-Kings’ plans to take advantage of the chaos.
Darokin: Chaos Returns. Mystara adventure. Parts of Darokin keep turning into a quasi-nuclear post apocalyptic landscape, only to revert back to normal after a few days!
Mutant-megafauna riding cavemen, flamethrower and harpoon gun-wielding ratfolk, sorcerous cockroach monsters, and robotic creatures rampage across the land.
Endgame big bads are the Oard, time traveling cyborgs from a possible future.
