Works with admin commands as well. Should also work with map rooms and obelisks.

And in theory they should teleport to the last place they were told to stand guard if you get them to stop following you. Like say ordering another thrall or horse to follow you, which will cause the last one to stop following.

Of course doing that means leaving them up there scouting for a short time until they decide to return home. But it might be worth a shot if you can’t teleport for whatever reason.
