That new trailer with Alexander: Midas reminded me of the Moblins from XI, and their underground city. And I recall during Chains of Promathia they mentioned they were seeking a great "iron colossus" underground. It was later revealed in the next expansion that the iron colossus, Alexander, was actually in Aht Urghan. They were digging in the wrong place, but that story thread never got picked up after that.

As much as I see complaints about goblins being "not as serious as Coil", I'm wondering if the story arc of goblins and Alexander in XIV is actually based on unused story ideas for XI. Almost all the Illuminati (even ex-member Mutamix) appears similar to the moblins.
