Could Drakkar be a former champion of the deep sea dragon that was coerced into joining Jormag?
We haven't really seen evidence of this before, but considering what Jormag is trying to do with us, while maybe not as literal as Teq, as the champions of Aurene.
Just a random thought.
I also found it strange during the story and the encounter, Drakkar moves through the ice, but when you melt away the ice there's just rock behind it. So, how is this huge dragon moving through a 10 foot thick sheet of ice with solid rock behind it? Like his physical body just merges with the ice and moves through it like a ghost in a painting of a horror flick, or a mirror.
It's also a little strange that it's all rotten and decayed. I guess Claw might be as well, but I always just assumed it was formed from fragments of ice and not necessarily a creature that was warped from corruption. I don't think I've seen any other minions of Jormag possess the ability to just traverse through ice like that either. None of the Svanir or Icebrood seem to at least. So what's so special about Drakkar? Could that ability be part of the reason why Jormag wanted him? Or did Jormag grant that ability? Would be convenient to find something that can traverse through water/ice if you plan on freezing everything. Not as convenient having a bunch of minions bound to walking/flying.
I mean, he's pretty dead now so I guess it doesn't much matter, but the idea of Jormag having this champion that spent a vast majority of time frozen in a body of water and presumed aquatic seems a little weird. Unless he's just some insanely large amphibious river drake that was empowered.
