So I just started Part 2 of OB, and something has been confusing me since the end of WOR/Start of OB. How do they infuse spheres at Urithiru? I've read multiple times that the city is above the highstorms and they are never concerned about the Everstorm because they are above it. So how do they infuse spheres there if the storms never touch them? I may have missed something and would like some clarity. Thanks!
