Just becuse I think that the gnomes are the most underrated race of the game, I think that they deserver more Lore and love
So
"World of Warcraft : Marsh of the Golems"
Story:
After Siege of Ogrimmar and during the events of WOD, the gnomes taken a lot of the crazy Goblin Technology and manipulated Titan technology from Ogrimmar and started to make some experiments
They created an army of Golems that help them to do trivial jobs. But everything goes wrong, the central matrix that control the golems goes crazy and using its memory archives when the Titans created life, opens a portal to "The Factory" , a world where the Titans build they creations like the robotic golems, the earthen and the stone mogus.
This world is an automated world, with a lot of bio machines that become crazy after the Titan left this world for some unknow reason
Our mission is to go to this world and save the fabric of the universe
The world
Is going to looks something like that (mirrodin world from the Magic series):
A new class
Tinkeeeeeerrr!!!!
I think that this would be cool, I mean , we have an "other world expansion" (BC) "Ice and nordic expansion"(WoLK) "Post apocalyptic expansion"(Cata), "Chinese expansion" (MoP) and "Back to the past expansion" (WoD)
This will be like "Futuristic Expansion" without relaying in time travels
What do you think?
