lets here some ideas or possible main story line predictions for Dragonborn DLC, the teaser picture has been released, what do you guys think ?

Okay, something I've mentioned before, but I bet that it will be drowned out by the incoming comments. I believe the DLC will be underwater based, or have serious underwater themes. The reasoning for this is Benthic Lurkers. The Benthic zone in real life is the lowest ecological zone in a body of water. I doubt that Benthic being in Benthic Lurkers is just a coincidence. Plus, Hermaeus Mora. There are a lot of patch details mentioning him and his realm Apocrypha so I think we should consider it a very likely possibility we will be visiting Apocrypha and Hermaeus Mora is majorly involved in Dragonborn's plot. Besides, he takes the form of a giant tentacled squid-like thing (most of the time), and the quest headers are that of what seem to be squids, or squid-like heads. And the so-called "Dragon Priest" in the teaser pic? The helmet he/she is wearing looks far more like a squid-like helmet to me. With Hermaeus Mora involved, I think this might be a priest of Hermaeus Mora, who is actually part of the Nordic Pantheon by the name of Herma-Mora, so that might explain the Nordic influences some see in the armor.
