I am not familiar with this quest but you mentioned in your comment that you think you were standing where the water comes to close the room. This is a common scenario in Tibia when there are map changes. If you are standing at a location when the map changes and would cause your character to be within an object it will teleport you to the temple with the message you quoted. "You had to leave the area because of strange events".
This can happen in several areas so I imagine it is what happened to you. It also happens in Oramond raids if the walls have been destroyed and are rebuilt when you are standing there. Also, it happens in The Cults of Tibia quest when you are summoning the Misguided Shadow when doing access to The Souldespoiler and all the gold disappears from the map. When the map changes back and if you are standing in a gold pile you will be teleported.
