This version of Anji Autumnlight is still in the game post 5.4, but now only gives the quests The Crumbling Hall and The Thunder Below. Those quests are the criteria for One Step at a Time.
The NPC should not be taken into account in regards to lore. (See Embodied Misery.)
Arguments have cropped up as to whether Anji Autumnlight actually perished or not, so I'm striking the latter portion of my comment until it's cleared up.
