Anyone who likes to be surprised by the presentations of ZOS, do not read, because I am almost sure that I am right, somehow.
Well, last year we had the leak of the Gloomspore Crate card art, and many people discovered that Blackreach was our destination, right?
This year, we had a new leak: the Potentate Crate. Normally, we would associate this with either the Second Empire, or with the Akaviri, right? But Crate's art is undeniable. It has red rubies, a red crest like imperial helmets, and golden details.
If that's how it was this year: Crates themed with the DLC, then, well, it's almost certain that next year we will be heading towards some part not yet explored in Cyrodiil's ESO.
Hammerfell would be cool, and I hope to still have something from Hammerfell next year, as Hammerfell was mentioned a lot on Greymoor. But with the existence of these cards ... well ... Hard to find that it could be anything other than Cyrodiil.
