you need to visit bareshade with him, then sleep until morning - beware, i think that nightmare sleep until mroning keep interrupting how q work and it is bugged, so i just sleep until morning and reload until nightmare doesnt trigger, and it triggers Ste event instead
It doesnt show up, the only active quests i have (mainly cause its still a WIP) the northcrest, rat problem and full moon. Unless i nee to clear one of those then i am locked from the quest.
