Replace the character, Sylens, for a new character, Sykes 😁😁. Just kidding, I have no doubt that it was due to autocorrect. In saying that, recast someone else to portray Sylens. Not sure who I would want to replace him. Maybe Idris Elba. You couldn't just end Sylens story. His story is intrinsically intertwined with Aloy's. And, not too keen of going down the AI route.
