Yeah, I’ve already hypothesized this. I think this is almost definitely what will happen and I would wager that the next set of darkness powers we get will come from her.
Beat me to it, she was offering alliance in Arrivals against the Darkness
And she has never directly threatened humanity,or shown any interest in our destruction,the slayers of her kin are curiosity's to her more than enemies
I think the boss of witch queen will be Xivu Arath and we will get relics or buffs from Savathuun to defeat her, or she is the boss of the raid , and a successful clear results in a compromise between her and guardians instead of the traditional kill it usually does
Well the implication atm is Quria will be at the end of this season or maybe the next, since there’s literally a triumph for defeating “the vex mind at the center of the endless night”
