How Does Magnus Die?

Don't really have the same offer for magnus that i did for taco and merle um i just have a question which is how does magnus die. I kind of envisioned him from the beginning as like a guy who was looking for a cause worth dying for. Lucretia's sitting in a chair at your side and karaon killian are there too this is just like taco and merl, they're there too when they're with you.
