Not everyone who plays appreciates all the artsy immersion stuff. Some people just want to feel powerful and unique. As if they're cool. As if they matter.
Big background stories help with that. This is your chance. You can be a powerful wizard... perhaps even a challenge to the gods themselves. And in your chest is an orb of ancient power. Only you can learn to control it.
it's like, alright, hell yeah, I'm a badass. Who are you playing? Oh, a pig farmer? In overalls? Okay.

The rub, of course, is that this grandiose character might just be your companion. As opposed to your main.
While plenty of players want to feel powerful and unique, they can also feel left out when some of the attention strays away from them.
Why are you looking at Gale and not me??? I wanna Netherese orb in my chest!

That all said, sure, there's something to be said for playing a nobody character coming from nobody roots.
I was just imagining playing the game as Mayrina's brothers. How great would that be? You and a buddy get together and take on the role of the brothers. One of you grabs a pitchfork and the other takes hold of a cleaver, and off you are, going to save your sister from her own dumb, albeit tragic, decision.
Of course, the difficulty level would have to be lower, but it's a game I would thoroughly enjoy.
But I'm one person. One. Compared to all the thousands upon thousands of people who would look at that same story and say, "Gosh, wouldn't this be cooler if one of us could teleport and the other could regenerate?"
