Getting to Nahpui Quarter?

I brought my R/Mo from Prophecies and started the Factions campign. I finished the Vizunah Square mission, and need to move on to Nahpui Quarter. I have ran myself to The Market Place, and tried running to Nahpui Quarter, but one of the portal things that I need to go through is blocked. I'm assuming that there is a quest that takes you there. Can anyone tell me which one it is?

(Sorry if it is a stupid question, but I haven't played in ~1 year.)

You get the quest in "Dragons Throat" (where you get dumped after vizunah). Then you do that one - "Closer to the Stars" I think it's called - that opens Nahpui as it takes you there.
