Azjol-Nerub: Forgotten Deeps is a merge of all three Azjol-Nerub maps from Frozen Throne campaign, with edited and added terrain. There are four sides: dwarves of Doorward, faceless ones, nerubians and the Scourge.
Arcane Planes is a Foundation of Durator stiled campaign. Its about an order of mages named Ronae Tor lost in another world, after their headquerters in Azeroth were attacked by the Burning Legion during the Third War. They appeared in a jungle world in a ancient titan gateway, after their teleportation spell failed. They created their new society in the jungle, using only magic. Its actually quite intersting, especially because they understood how to use the gateway to travel to other worlds. I can tell you more if your intersted after. Its big and intersting story.
