In the game Honkai Star Rail, there exists one of my favorite science fiction worlds. Although I’ve mostly stopped playing due to its increasingly predatory gameplay, I still love the lore.
In the HSR universe, someone who reaches the highest point of an ideal ascends and becomes a deity known as an Aeon. They preside over their ideal, or “path” and grant strength to those who believe in it strongly enough. Paths include The Hunt (decisive perseverance), The Erudition (pursuit of knowledge), The Nihility (nihilism), The Beauty (self-explanatory), and my personal favorite, The Elation (existentialism) among others.
The Elation is presided over by the Aeon Aha. It is described as such in game:
“When the Aeon of Elation climbed to the highest branch on the Tree of Existence, they saw the cold and despicable void, the stars operating like machinery, and how the meaning of all things bows before nothingness. They continued looking until they saw a baby fall to the ground and cry because it had been wronged. The Aeon burst into laughter, laughter so clear it tore through the cold universe and still reverberates through the universe today.
[Followers of the Elation] believe that the truth of the world is a joke, and that the ultimate meaning of all things lies in mere laughter. The universe is merciless, but there is joy to eliminate pain, dilute sorrow, resist nihilism, and heal wounds. Laughter, the gift of intelligent races, is the only answer.”
Many of the followers call themselves Masked Fools. This has a double meaning, as they like to take on the role as the universes jesters. They are also disregarded as fools by those who cling to things like love, wealth, and success. The parallels to the lecture on existentialism are clear.
