7th Calamity aether connection?

[LineageRazor]

so if I'm understanding correctly, Light on the First is causing aether to be dulled or stalled. Would that mean that Dark on the shard that died (the 5th iirc) that would've been overactive aether, overcharged?

WHOO this calamity stuff makes my head hurt

Yeah, Aether was overcharged/overactive on the shard that became the Void (the 13th), and that's why it's so chaotic there. It's overcharged to the point where it's now unusable, both to the Ascians and to the twisted inhabitants (who now have to invade other worlds in order to find Aether they can use).
