Nox decides to make his way to the Owens home planet to participate in court in the spaceship the Owens gifted him. Along the way he runs into the final two Owens, who along the way also take spicy good care of him.
They build up a golden castle??? I don't know what that parts about. Also, story starts to take a heartbreaking turn from here, so just a warning.
The last Owen was called the Lord of Sorrows. He's the protector of all the dead versions of Nox across time and space, across all the timelines.
Yes, Owen has always loved and protected Nox and tried everything to save him in every lifetime. A very heartbreaking one-sided love, that he left as this Nox was very different from other timelines and didn't love them back (didn't realize it didn't show up, but the Owens took as not in love with them only needing their support).
The new Owen and Nox arrive and he meets his daughter Noi. Apparently he feels an instant connection and falls in love (parental love, please don't twist it). He realizes even more how much he loves the Owens and how much it hurts to be apart from them.
Now, I don't know much else besides it states that "Owen missed Nox so much he wasted away." And that Noi was on her own and so lonely and Nox understood that same loneliness and connected to her because of it.
