Brandonnn: Like Felix said, your description of the quest reads exactly like mine, up until the murder. It doesn't last. Go back to the tower now and check if they're still alive.

Ahcos: Tenpenny Tower never really affects the game in any way outside of itself, but in this singular instance I don't think it matters. It works as a self-contained experience. The story's important by itself, I think I like that it doesn't have to do with the main plot, and doesn't help you one iota in your quest to save the world. What I like most about the choices you make is that it's different than "kill the end boss" or "slap the handcuffs on him."
