Can anyone help me with my backstory?

[Savaroth]

So, my character, an Aasimar Shaman named Savaroth is a part of a group of seven in a campaign in Cheliax. I have a backstory partly made so far, but I need a few extra details that would make it really good.

This is what I have so far:

Years ago, his significant other (for lack of a better word in this world), Haith, was taken by a mysterious enemy who's race is unknown. Haith's familiar, an owl, was killed trying to follow her, and Savaroth made the Owl his spirit animal as a dedication. His quest to find her is what drives him, and he has also learned that the mysterious enemy is hunting him as well. An anonymous tip told him that this enemy is in Cheliax. Savaroth traveled to Cheliax to try and find him, which led him to a group of 6 others who are at a protest, but not for the obvious reason.

Any thoughts? Thanks to anyone who helps!

I assume you are playing Hell's Rebels then? I believe the protest is the intro to that campaign. Then I assume you are also playing a good character, either Neutral Good or Chaotic Good since Lawful Good usually doesn't fit the vibe of the campaign (though they make accommodations for them).

The easiest ways I find to make a good background for a character is to imagine how they gained their powers, and work backwards. What event triggered the awakening of their gifts? What about that experience broadened their view of the world enough to willingly risk their lives in the most dangerous profession in the world? Then, how did they come to that point?

Was it a dare that lead them to it? Was it chance? Curiosity? Was it the thrill of danger and the sense of invulnerability that comes with youth?

How does your character see the world? Is it a wonder to explore and experience? Is it full of people that need help? Or are they tools? Playthings that only exist for your amusement?

How about the character's family? Did they have brothers or sisters that made them more competitive? Were they an only child seeking to impress their parents with their talents?

Try and found how how your character thinks and reacts, then try to reverse engineer events that might have influenced them to turn out that way.
