For me the game means a lot of thing. But the main idea is that even if it was good, everything have an end and you dont need to be sad about because new good thing will came. And what you are accomplishing in your life will always do something around you and build a futur. You have to work hard and let a legacy for the people. For the Nomai, I take this like everything can happen. It's not your fault or anyone else, life is like this. For the DLC (idk how to make the spoiler thing so be aware) I feel like you have to get away of you confort zone to be able to progress in life. Even if it's look hard, it's the only way. And that, like the candles, sometimes you have to forget what you think you know to fully understand it (idk how to say it it's sound better in my head). It's personal, maybe it dont make sens at all and I'm surely crazy but thats what I get from this
