and interesting note: it seems more totems of Hircine were added in. This leads me to believe these upgrades will be accessible through the companions.
Geez. So far in the Elder Scrolls we have the following; Totem of Claw and Fang(Bloodmoon), Totem of Brotherhood, Totem of Fear, Totem of the Hunt and the Totem of the Moon. What more?

I would like to see this Harkon he probably found his way out of the Soul Cairn. If that's the case he could be Lord of the Volkihair vampires and they have returned from there as well in full force.
Maybe. In the preview, you can see him standing when a portal to the Soul Cairn opens up leading to that dimension.
