Abnur Tharn's literal last words after you arrive back in Grahtwood are "I'll send for you". So... go home to Daggerfall, wander around, expecting some kind of bread crumb to Elyswer. Nothing. Looking for a quest starter in my UI, nothing. Ok... ZOS fail again. Break out the Google... Oh you have to travel to Rimmen and find someone to talk to you.. Awesome job Zos.
Had this problem before, and apparently will continue to have this immersion breaking storyline breaks.
