This is JUST speculation.. ideas/theories or just fun stories for being to come up with about the module 12 update that is rumored to be just as big or bigger than Module 6. This is purely a discussion for everyone to have fun and come up with different ideas of what Module 12 just might or could be. Any concrete information is appreciated but this mainly for fun speculations! I will put up what I assume might be a module 12 or module 12 worthy story, but someone else can either add on or create their own idea of what it could be. Also if a developer sees this be sure to read because you might have fun with it haha. I also want to add I am not the best at English so sorry if I mistype or sentences are run on or do not sound right.
Module 12 a big ole baddie coming to us in the future! From all the twitch watching and hint dropping over the last several streams it really sounds like its gonna be a large update full of neat stuff. I suspect we will see a fairly large raid battle and a return of another lost dungeon. HOPEFULLY a new class will be involved in Module 12, and it sounds like a new race "might" show its face.
I've seen a what appears to be a theme of content being released. Module 8 and 9 are part of the whispering caverns, Module 10 is of Icewind dale, Module 11/11.b is of The chasm, and Sharandar. I am making a guess here on the Main story of Module 12 (or at least a story I think would be awesome to see).
Module 12 will hopefully be based around the history and lore of Mount Hotenow, and the story of the legendary forges (Gauntlygrim) the adventuring party that rediscovered it. (Valindra was included in this party so would be cool to see her background, before becoming a lich.) The story could involve Maegera the Inferno fiery primordial, who was mentioned throughout Hotenow quest line, and the Fiery pit where he is asleep. He was awoken once already and Drizzt Do'Urden, Bruenor Battlehammer, and Jarlaxle Baenre put him back to sleep. The history says they did not restore all of the water elementals since one of the summoning locations was broken, so this had a affect that only put him to sleep temporarily. That he is now waking up once more and cause a lot of chaos across the lands. The quest line could be started by Bruenor who has felt trembling s in Gauntlygrim as of late, and consults with drizzt that he fears Maegera could be awakening. Or started like there was a large explosion at hotenow and causing lots of destruction.
Anyways this would be a great chance at restoring Caverns of Karrundax back into the game with some after affects of Maegera awakening like a new pair of fire scorpions, and using those new fire giants kabal created. Maybe Gammoth being "reforged" and coming back as a higher being commanding some sort of powerful fire creature. Also having to fight Karrundax again but instead of just karrundax he summons another fire dragon to his side where you fight two fire dragons at once. (OR he summons an ancient dragon because the ground ripped open from Maegera awakening to the ancient caverns below releasing these ancient dragons!) Would be cool to see Wyverns as a add to fight as well in the dungeons or raid boss battle.
Also a cool mount that could be added in this is like a fiery rage drake, and maybe a fire scorpion mount.( I know that would be a lot of moving "parts" but you guys did it with the spiders.)
Also a wyvern type of creature as a companion and mount.
I could go on forever but cant haha... Here is a shortened list for the people who do not like reading.
