Masteria Quest: The Right Path

In the latest patch they gave us the old NLC area. There was a quest called "The Right Path" and after doing that, it would allow you to use "Joko’s Badge Rewards" and "Fiona’s Forge". But I'm not sure on how to start this quest again. Do I have to do all of the NLC quests involving Icebyrd Slimm to reach up to that point?
I checked Hidden Street for the pre-requisites and it only gave me "The Fallen Woods".

Could anyone help shed some light on this for me?
