Analysis of Elation and how Aventurine's arc will go
This will be an analysis on the playable path of Elation and how or why specific characters are on this path. (This is simply discussion and theory for fun)
To start with the basics, how did Aha ascend to Aeonhood?
A parable mentions that: "Aha climbed to the highest branch of the Imaginary Tree, and THEY saw how meaningless the universe was. THEY continued looking until THEY saw a baby fall to the ground and cry. THEY burst into laughter."
So in short, Aha isn't simply about laughter. Aha is the combination of staring into the void and laughing despite the meaninglessness of it.
Enlightenment + Joy. Elation is feeling of joy but also comes from the latin root word 'elatus' which means "lifted up".
What does this mean for our characters?
With this in mind, let's take a look one by one at each elation character. (Note that there is faction path and personal path. I'll get more into it later).
Yao Guang
Yao Guang is a Physical Elation character. While she is a general of the Xianzhou Yuque (Faction Path of Hunt), she herself is on the path of Elation (Personal path). This is due to her powers of being a diviner, able to see into the various futures. She is enlightened by being able to see into the future but she also jokes around with Tingyun during 4.0, she's able to enjoy the joys of life despite the misfortune hanging above her head.
Sparxie
Sparkle is already is part of the Masked Fools (Faction path) and a chaos gremlin (Personal path). But while we accompanied her during the Tavern, we heard her monologue when she was stuck to the hospital bed. She laments about how meaningless the universe is and how the masked fools gain a new perspective when they put on a mask. Enlightenment. When she confronted Sparxie at the school and she was told that she was the abandoned mask (up in the air, either way they merged back anyway). What did Sparkle think? She thought that it was cool. She was happy despite confronted about the meaninglessness of her existence.
Evanescia
An Emanator of Abundance that Aha put on Planaracadia. At first she simply searched for immortal life, starting out as a "beast of blind love and hate" but Aha promised her enligthen her and teach her the meaning of true joy. After being the arbitrator of the games, she gained an new appreciation and love for fleeting life and the joys of it.
Silver Wolf 999
She literally is at the pinnacle. 999 is her limit before she reaches to the level of the Aeons. Despite being confronted with the meaningless future Elio foresaw or being stuck at 999, she joined the Stellaron Hunters to make her own future and even have a little found family.
Now what about Aventurine?
I can't say anything for certain, obviously. But we can speculate with the information we currently have. Perhaps while he is searching for the traitor in the stonehearts (mentioned in the livestream), maybe we come to learn and experience how much Penacony changed and affected his viewpoint (at the end of 2.1, he talks to a younger version of himself and confesses that he's not ready to meet his family and plans to prepare for when that time comes to make them proud). Perhaps he's finally learned to not just live, but to live for himself. Or maybe he learns something deeper about the IPC and a means to finally avenge the deaths of his family. Who knows.
There's even Pearl but I'll leave that to when 4.6 is almost here, but with this information I'm sure you can make your own theories about her.
