Aspects, Voidborn, Aurelion Sol, Riot pls

This lore is so huge. Some questions rise. We have a new kin, the Aspects, what are they? Something on the void dimension is confident enough to laugh at Aurelion Sol. What is that? A battle between super powerful beings (Aurelion and the void guy) is coming? And my personal question, where are the Watchers? The last time they were mentioned was in Bard's release. Will they take place in this choreography full of God, demigods, inter-dimensional and celestial beings? Inb4: Ragnarok.
