Seth created a bubble with ten layers of mind forced to extricate himself from the effect of the dimension. He immediately felt the difference and he also felt his actual body. It was actually due to the Aura Tome in his body that his aura was resisting being siphoned completely.
Another effect that was happening was that the Tome was absorbing the dragon's aura and converting it to his aura and then fueling Seth.
This was in a way, that the bones of the dragon pulled Seth's Aura and the Tome pulled back and got them back and absorbed the dragon's aura, at the same time converting the dragon's aura to make sure Seth had more reserve.
As Seth looked up at the dragon, her eyes made him have more understanding of what was happening.
It wasn't what he felt, but rather they were both trying to convert each other's aura. However, Seth was losing because his mind will eventually be corrupted with moon smoke and that will be over for him.
