There is a few flaws with this. The native dragons, they weren’t cult like, they were following instinct. It’s who they were. Someone outside coming along saying “you could be different” is very alien, agreed.
But the solution to imprison your siblings, it still has no basis. Most people don’t realize, but prison isn’t supposed to be “time locked away, staring in the corner.” It’s actually called rehabilitation. You are trying to reform the inmate. The Aspects made no attempt to suede their peers to seeing “order.” The just put them in perpetual stasis.
So again, what was the plan? Feel bad and submit?
