So in the Dark Brotherhood DLC you encounter of group of people that [and I'm paraphrasing here] kill certain people to prevent events from happening, the quest hints at something going on in Vvardenfell [This was before the Morrowind DLC]. But in this quest the group is trying to kill Nayru because something her children well do. Is this a hint at the DLC after the 'Triad' [Morrowind, Clockwork and Summerset] Arc is over? Or is this some Elder Scrolls lore that I'm not understanding?
