Tristana Full Bio?

still doesn't have a full bio and I don't see it mentioned anywhere really. Has she just kind of been forgotten?

I mean, her current short lore kind of makes her the most generic character ever since it is never really expanded upon.

Greatness comes in all shapes and sizes, as proven by this diminutive, cannon-wielding yordle. In a world fraught with turmoil, Tristana refuses to back down from any challenge. She represents the pinnacle of martial proficiency, unwavering courage, and boundless optimism. For Trist and her gun, Boomer, every mission is a chance to prove that heroes do exist.
