Helot

You slam your staff onto his head until he is dead.

"Now, to show us all why we should be loyal to Eurid!" You pick up Tathgor's body and carry it over to Eurid's estate.

Hanging on the wall is a torch. You pick it up, and light the body. It goes up in flames.

And everyone saw. You have made your statement, and you finish your life as a helot. Some life.
