Nial knew that it would be impossible for him to trick Silvian forever.
Simultaneously, he could tell that it was useless to force himself to separate his own memories from Damian's.
It was possible to do so, but Nial could tell that he could learn a lot from accepting Damian's memories as his own. Not only would it allow him to imprint everything important deeply into his mind, but the mistakes Damian made in his life would always remind him of what he should never do wrong!
'Now I get what the God of Darkness meant when he spoke about the Odyssey seed taking over my mind, and that my willpower would be a deciding factor in knowing whether Damian will reincarnate, or if he will find his eternal peace.' Nial thought, understanding that the memories he had just seen were bound to change his behavior.
Even if he knew that it was not his life, the memories of the God of Darkness felt like Nial had lived through them all.
