I admit we were only given a few seconds of footage showing it, but I thought when the Star Shrine on Ragna was destroyed, the feedback completely shut down the Wind Shrine on Windermere, hence why the lights on Windermere's tower went out.
I thought we were supposed to take Mikumo's flashbacks as the genetically-inherited memory of her Star Singer template from thousands of years ago (which of course from a real-world perspective genetic memory is bullshit, but sci-fi stupidly loves to use it).
The bombing of Carlisle is a bit confusing to me. If Wright's superiors wanted him to bomb Darwent, and they managed to remotely seize control when they realized he was trying to deviate, why drop it over Carlisle? Last resort second-best choice?
