So in the 4E world, these thigns were created as part of the Spellplague.
In my Neverwinter campaign, the group was going to use one that near the city as a base, The Pirates Skyhold. Is there any new news about them failing with the end of the Spellplague or subsequent events?
Anyone have any other references to them by chance?
Akanul still maintained its earthmotes after the Sundering per the SCAG (think that was the source). There's nothing that says there might not be other areas.
