Word of warning, at one point you have to talk to a Techeun before you enter the final fight of the mission. But, after awhile all this stuff becomes stagnant and repetitive (just like the Dreaming City Curse). If you skip talking to her and go straight to fight the final boss and defeat it, it won’t end the mission. The portal to go back will disappear, you will still NEED to talk to the Techeun and conveniently the other elevator to go up and out is down for repairs. You will have to restart the mission again if you fail to talk to the Techeun.
