"... It just feels pointless," Daud finishes, "I know. I understand."
Probably more than Octavo realized. A tool- a piece of property, kept captive and beholden to whims of powers beyond you. All one could do was obey or fight.
"My mother was taken from her people by pirates," he informs, "To be sold as a slave. She endured the unthinkable, and escaped. Had me only a few months later."
Putting it nicely. Daud crossed his arms, looking at the ground, "When I was ten, I was followed home from school, and taken by a man that wanted use of my quick hands. My mother died fighting. For years, I trained, obeyed, bided time to make an escape, and killed my way out. I fled to Dunwall, joined a gang there, and was eventually set up. I got caught, thrown into Coldridge, and later sold as labor to a whalehouse."
He looked up, "I really wanted to change my situation. I wanted to be out- in control of my own destiny, make some kind of difference. I was only when my friend was about to be killed that I got Marked by the Outsider- a god, and given dominion over magic. But I didn't ask to be marked."
He sighs, "I don't know if any of the others did, either. I don't know if he ever spoke to them the way he did me- and even when I tried to turn my life around, leave the killing behind, he wouldn't let me be. I always wanted to believe that my choices were my own, that the consequences of my actions would be mine to bear, that I truly had agency- but after what I went through? Knowing that he could see what I would become the entire time? Steering me to intervene in a witch's plot? Showing me visions of what was to come? Cryptic nightmares? I started to question if I truly had control all along. I'd been used, I'd been had by my own nature."
In the end, he understood that the Outsider chose him in hopes of ending the bound gods existence, one way or another.
Daud wouldn't forgive being used, and driven to death- but in the end, Billie's own peace meant more to him than vengeance... and perhaps, it was fitting to make the mortal live in the chaos of the world he helped shape.
"Don't give up. It is worth it to keep searching," he says, "To keep fighting for your agency, no matter how exhausting. Even it kills. But it's also important to rest where you can. To recover. Or else you won't be able to fight where you need."
Daud lowered his arms, and growled, "I do have a mind to kill these Stars. I might not know how- yet. But I know everything can die."
