Skipping the labyrinth after defeating aspects of Haas...?

[Jamers]

After I finished killing the 7 aspects of Haas and returned to the green dragon at the entrance to the labyrinth area, he says that he'll teach me a magic phrase or some method to skip through the labyrinth and travel freely to and from Murock.

Anyone know how to activate this magic phrase or whatever? I tried walking through a bunch of the entrances hoping to see some pop-up window asking me if I wanted to skip the labyrinth, but no such luck. I've ended up just walking through it to get back and forth. Anyone know how to activate this shortcut?

Thanks!!
