The legacy of the Giant Dragon must be unlocked and organized through each slumber to transform into knowledge they can master.
Even a Divine Spirit's offspring would be overwhelmed by receiving all the legacy information of the Giant Dragon at once, let alone these young dragons.
Perhaps each dragon needs to attempt their own Divine Sealing Dragon ritual based on their specific situation, with each dragon requiring its own unique method, resulting in the absence of specific knowledge preserved within Karon's legacy.
Regardless, this knowledge would not exist within every dragon's legacy, and the world's disparities are vividly exemplified here, perhaps because those dragons who have transcended this step did not choose to pass down this information.
This is natural—dragons are inherently greedy and selfish; their nature is unalterable, caring not about the aftermath once they are gone.
