Final Quest

The knight turns his helmeted head towards you as you approach.
"Can you tell us anything about this arena?" you ask the knight.
"Its dangerous," the knight replies in a low, slightly accented voice. "If you are no warrior, you should not be here. Everyone is here to fight."
"Why aren't you fighting?" you ask.
"I just want to leave," the knight answers. "I still remember who I was before. But I can't leave. None of us can, until there is only one left."
What do you want to do now?
