Some of my moot have a great idea on suggest, turning your sona into Forsaken.
So I manage to take a little bit of his lore and work and maneuver to be able to fit into Forsaken.
To make it a little backstory, Shooting star. Instead of living in space like his original lore, he spending most of the time, wandering on Earth, trying to pick up his memory or finding it.
But there are one crucial rule that most star must follow and that's to not lose control. Those star who couldn't move on or lay rest on their past will turn into Blackhole or disappear forever and be forgotten.
So Shooting star spend years, soon he learn his past and it ruined him. He cannot move on and it making him insane everyday. And because he got no one, no therapist and nobody to help. He fallen deeper into deep depression and deep end. The only thing that keep him or help him find a little bit of solace is religion (in forsaken version of course, cult basically.)
Believing it and completely put his heart and soul into it. It still wasn't enough that he began to crumble.
And before he finally feel himself vanishing or becoming something else, all he wish for is to forget everything.
And that's where he finds himself now, In a new world and revived into 'forsaken' world. He had no idea who or what he supposed to do, what's the goal. But all he know is that he can't talk and can't walk. All he do is floats and go around to find anything that could help him find his memory back. Slowly and unknowingly repeating the cycle of his psychological horror.
(The reason why his mouth is sewed are tied to my Sona having speaking anxiety. And a little from Autism where I can only smile and only express my emotion through words or eye contacts.) (I hate it.)
And from his original lore, the only way he can die is if he couldn't control his negative emotions. So he's practically immortal.
In forsaken however, it works different. He still be revived and alive.
The only problem is that the giant beartrap that follows and help him, they are also responsible and the spawn able to control it freely. So when ever BrokenStar remember pieces of his memory or failed. They'll chomp and eat his head, forcing BrokenStar to return and not having any memory from before at all. And the cycle of BrokenStar amnesia continues so much that he began to not able to understand his emotions.
So much so that he had no idea why he's afraid of something or doing things that he never knew before.
Luckily for him, he's not alone this time and he got a little friend who will always stay by his side and will never leave him!
It speaks for him and give him a new name. His new name are now BrokenStar.
