in the reveal stream we can see scorn in the throne world at around 1:20:33
obvious implication is they're going to be involved in the story in some capacity
since we already got 3 hive raids with crotas, kings fall, and crown of sorrow, im guessing the raid will focus on the scorn instead, with possibly fikrul himself as the final boss
i bet the end of the season of the lost we will fight savathun's worm. as for the witch queen raid, i don't think we will be fighting the anomaly, because that is the overarching villan that certainly has to wait till the end. savathun wont be the boss either, ad the devs had said. it could possibly be fikrul, using a recurring character just like taniks. it could also be xivu arath, to tie up the third sister narrative. i personally think it will be xivu arath, because its known that she is being controlled by the dark, and has domain over both scorn and taken, given by the dark. perhaps the raid is xivu arath attempting to get even more power from the pyramid, and we have to stop her? or something is emerging from the pyramid into savathun's throne world, and we are trying to stop it? i think savathun is going to become a character akin to mara sov, and less like oryx. i dont think we are going to end up killing her.
