Can somebody explain the last

So everyone in the past that's connected to taehyuk has been reincarnated. The advisor to the king kept getting reincarnated (with his past memories) cuz he got curse ( made to suffer and everyone else around because he killed past taehyuk). So the advisor kidnapped taehyuk and pushed him in the ocean in hopes of causing the same suffering he had endured.

So now thats taehyuks life in danger the orb activated with the dragons memory. But it looks like the memories are being twisted and attaching with taehyuk soul( my theory)
