... so you could have 3 active locations on the last stage of the Watcher in the Water quest!!! This is alsmost like teleportation...

how come?

He means The Ring Goes South. You can have 2 active locations at the end of that quest. But I don't think there is a way to get 2 immune active locations, so you wouldn't be able to move a 3rd down there.

Played Drowned Ruines yesterday. While playing we were instructed to make Shrine of Morgoth the active location. At this moment we had another active location, so i simply added Shrine of Morgoth so there were two active locations ... played right?

As an addition there the quest card Sahir's Betrayal does instruct you to " Make the set aside Shrine to Morgoth the active location, Grotto side faceup. " However it does not say "return any active location to the staging area" like for example the second quest card in Watcher in the Water did.
