What Is The Difference, If Any, Between "Permanent", and "Until Dispelled"?
Can a permanent teleportation circle be dispelled?
Answers to first one says it can't be dispelled, answers to second one says it can. Questions are close to being duplicates. If I'll try to ask which one is right, I'll essentially post a 3rd duplicate, and it is not useful to keep answers based on one set of sources in one place, and answers based on another set in another place.
So how would I go about looking for some kind of consensus? Or at least showing that there is no consensus, in a way visible to readers of both questions?
