There is a moment in every game against Arkhelios Dragon where you think you've won. Your opponent's Shield is at 3. One more hit. You swing. And then Cosmic Collapse triggers.
When Shield would reach 0: prevent it. Deal 20 damage. Restore 15 Shield. Inflict Corruption for 2 turns.
The trap doesn't just save Arkhelios. It punishes you for winning. It takes the moment of your greatest triumph and transforms it into a 35-point swing — your 20 damage dealt, plus the 15 Shield restored, plus whatever the 2 turns of Corruption will amplify on subsequent cards. The game you thought was over has just begun again, and now you're Corrupted.
This is Arkhelios's theology made physical. The Void Ones don't believe in fighting. They believe in inevitability. You can struggle, and the struggling itself becomes the mechanism of your conversion. Every aggressive move against the Void generates the conditions for the Void's response.
Lore-wise, Cosmic Collapse represents the moment when Arkhelios stops observing and acts. Throughout most of Book One, the dragon watches from the rift — patient, analytical, almost scholarly. But when its existence is genuinely threatened, Arkhelios reveals what it has been hiding: the signal doesn't just infect. It inverts. Your strength becomes its strength. Your conviction becomes its argument.
The five resistance heroes have never seen Cosmic Collapse trigger. If they had, they would understand what Sel found on the quarantined page of the Codex: the signal doesn't need to win. It just needs you to try to win. The effort itself is the mechanism.
