Kauan are amazing at creating soundscapes to a narrative or concept. The music takes you there, to those ships in the album art. I imagine that's why there's a role-playing game that goes with this music.
It's the same with Sorni Nai, I would highly recommend looking into the story behind the album as it creates so much more to the listening experience, you appreciate the music even more.
I don't have a favourite track because the album feels like an entire piece, maybe a favourite movement.
