Ritual of Returning

[SurvivalistMerc]

I understand that this spell is supposed to take you back to your home province when you are injured.

Two questions: If the injury is sufficient to kill you, does it kill you? Or do you get teleported prior to death?

Second, if you are "routed" and have nowhere to go...do you teleport home or just get destroyed the way you normally would in this instance?

Just curious and not able to find the answer elsewhere.
