If you were counting on meeting one of the last griffons in DAIII I have a bad news for you. According to Mark Darrah, the Executive producer of Inquisition, we would not see griffon riders this time, because it would not fit in the design and stylistic trend. The producers also do not plan any time jumps so there will be no narration of the type found in Dragon Age II. You can find the citation for Mark's Twitter in the extension:
"Not a steampunk setting -Still in the Dragon Age so no huge time jumps -no gryphon riding (sorry) -not a framed narrative ".
Wait. What does Not a Framed Narrative mean in this context?
"Da2 had Varric as a narrator telling the entire story (like Princess Bride) DA3 doesn't do that".
