Seems like they're preparing a new part of Time Temple.

Guys, instead of looking it from the story point of view, like I think it should be seen, you are debating Freed style and hair. I'm pretty sure is Freed, and I doubt that Evan will meet Mercedes soon in the story. But perhaps Afrien calls for Mercedes and tells her of the Hero Succesor.

And now that Aslemn told that, well, maybe we didn't saw the Black Mage at all, but the hooded character in the trailer was Akyrum? Seems way more possible.

If Freed is in the trailer..where is Afrien? The 12x-200 final growth of Mir cannot be Afrien. Afrien is huge, and I'm assuming was always huge due to being King of the Onyx Dragons..even when Freed was alive..Afrien was still huge. That trailer looks to be of Evan and Mercedes fighting current day Black Mage, least that's what my perception of the video was. The cosmetic of both characters is not important in my books. The dragon beside the guy would be though.
