Of course, we also know from Storm King's Thunder that Artus Cimber and the Ring of Winter play a role in an upcoming adventure. Perhaps they are one and the same.
Considering this text from the blurb for the latest SKT expansion for Neverwinter, I am not sure the Ring of Winter will show up in another print adventure if the characters in Neverwinter can get the ring:
"Sea of Moving Ice brings tons of new content including a new adventure zone, new ways to travel and new artifacts and trials! Assault the keep of Jarl Storvald and face down his army of giants as you fight to reclaim the Ring of Winter, travel between icebergs and among arctic seas with the Khyek outrigger boat, but watch out for dragon turtles!"
Now, I do not own SKT, so for all I know this is how the plot goes in it too.
