i think wyll should have been the one with the astral prism and i do actually have a line of reasoning to follow here
1. the githyanki's pact for the red dragons is with tiamat, who lives in avernus and was formerly its archduchess
2. hanging on to the astral prism containing orpheus would have been the ultimate insurance policy; vlaakith can't stab tiamat in the back if it means tiamat might expose her and free the prince of the comet
3. wyll made his pact with mizora to fight off a cult of tiamat that was attempting to summon her
4. "the astral prism was stolen from tiamat and zariel subsequently tasked mizora with retrieving it to make the queen of chromatic dragons shut the fuck up" makes more sense than "shadowheart and the sharrans stole the prism for??? reasons???"
5. shadowheart was being groomed as the eventual chosen of shar; finding the nightsong should have always been her mission
6. this brings wyll's backstory into the plot in a more active way and gives him an internal conflict to struggle with
7. most importantly: wyll desperately needs more content
