Tyrande is missing in action after Shadowlands. Malfurion went looking after her leaving Maiev and Shandris in charge (potential shipping here).
Night elven society is fed up with druidism and Elune after Teldrassil's burning as they didn't receive any help neither from Elune nor 'nature'.
Darkshore is plagued and in ruins even though Horde is driven out. Ashenvale is almost leveled with all villages destroyed.
A mysterious and potent figure appears within Shen'dralar luring remains of night elves to reclaim Eldre'Thalas making it their capital again and give themselves to Arcane again. They accept the invitation though Maiev and Shandris are hesitant.
A new leader, this mysterious sorceress, sends her newly appointed generals, Maiev and Shandris, for some dangerous tasks to Silithus and Storm Peaks. It looks like she has some unfinished business with the old gods. Thankfull, N'zoth has been dealt with and she doesn't need to worry about him anymore.
Fanmade or potential pitch?
