On Aradune, it seems impossible to leave TD no matter where you try to go. I've tried gating, potions, translocators, it always sends you to the succor point or disconnects you and then sends you to the succor point.
Did you try to return home from character select? Maybe try deleting the timorous zone file and repatching?
I'm binging on Twilight Zone episodes... your post frightened me. "Gloomrot unlocks a door with the key of imagination. Beyond it is another zone- a zone of sound, a zone of sight, a zone of mind. You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into the EQ_Catbox." Do you have access to Origin AA?
It's long since fixed itself. Was only a problem for the first 30-40 mins, when there were 800+ in zone.
