Why didn't anything happen to the Calimemnon Crystal during Karsus' Folly?
The Calimemnon Crystal sits inside the Spinning Keep of Siri'wadjen and is said to always float 40 feet in the air, to prevent Memnon's Crackle from reaching it, and has a magical barrier surrounding, to prevent Calim's Breath from reaching it, as said in Empires of the Shining Sea book. Now it floating isn't said to be magical so I will ignore that, but the magical barrier should've went down during the time the weave was being restarted right after Karsus' Folly. This would've been a perfect opportunity for Calim to reach the crystal and bring back his physical form. The traps and locks inside the keep are said to be of the arcane so it would make sense for nothing to be in his way.
Am I understanding this right or am I just missing something?
