I was kinda disappointed that the key of aaravos didn’t do anything in arcs 1 and 2, maybe possibly something in the unlikely event of an arc 3?
I was thinking that since the key of aaravos reacts to primal magic, that since aaravos was the only known being to have mastery of all 6 arcanums, he was the only one that could open it, and inside there was something that could help defeat him, or smth about is backstory. I also thought that by s7 that callum would learn all arcanums, so that He opens it in s7 and then they have a way to defeat aaravos thanks to callum, instead of just the archdragon going boom.
