I deleted it since I think that it's nothing. It's actually Young Storm DRAKE and not Dragon and they have a different model. It's an interesting place but I don't think its relevant
For anyone curious what it was: I went on my Shaman alt and entered the new Vortex Pinnacle to see what I can find out about Thunderaan and noticed a lot of 'Young Storm Dragons' flying around. I then typed 'Young Storm' into wowhead and 3 entries came up, of which 2 were from Vortex Pinnacle. The other entry is a lone Young Storm DRAKE (not Dragon) in Stormheim at the small Vrykul place 'Vrekt'. He sits in front of an abandoned building. When you stay around the Drake you'll notice that there's an unique interaction taking place in which a Vrykul NPC called 'Vrykul Mariner' (unique NPC just like all the others in that place) feeds the Drake occassionally.
My line of thought was that it's somehow possible to do something with the two NPCs in Vrekt but it doesn't seem to be relevant. You can't steal the fish, Parley and Bribe won't work or at least wouldn't result in anything and they wouldn't even drop loot upon death.
