Narron, I know about the VK group, but I can't join it because I'm from Ukraine. I know that there's a rider model available, but I don't have the ability to download it. And the vampires, liches, and especially the phantom drakes in the sixth game are cool.

And yes, for those who are playing the campaign in the sixth game, there are also dead dragons. In the very last campaign. You can also summon them with the Dragonbone Staff. I have one as my avatar. Yes, you can't recruit them in the city and all that, but they exist and belong to the Necropolis faction.
