So Drizzlewood Coast was the "Jormag Lair"?.

As the title says, far north area in Drizzlewood was the hipotetical "Jormag Lair" ? (the equivalent of City of Arah was to Zhaitan)?

Kind of, though not an equivalent to dragons stand or dragonfall since we didn’t kill a dragon there. Not sure how they’ll handle that if the part 4 to champions is like the last 3. Hope they add a new map, even if it’s one that’s only just big enough for a dragon fight and has nothing else. I can’t see a dragon dying, much less an epic battle of two dragons fighting being that exciting on a map we’ve been playing since 2012 and burned into our skulls from map comp

Arguably closer to Draconis Mons for Primordus or Vabbi for Kralkatorrik - somewhere Jormag just moved to, rather than where they've been situated for several years.

In Season 3, Jormag was established as being just beyond the Bitterfrost Frontier - this is why The Bitter Cold area existed as it did. It was so close to Jormag that it was freezing anyone who came close, even icebrood. Jormag moved at some point between S3E3 and being forced asleep, presumably to recover from the attacks as it went to a place of power: the Shrine of the Spirits.
