The black-robed man walked toward the two young men.
"Let's play a game between you and your friend, Biggie. Only one of you is allowed to live. Of course, whoever lives will need to leave with me. Make a decision now!"
The black-robed man might have suggested this 'game', but in fact, it was a trap. If Bel killed Biggie, Bel would need to leave with the black-robed man. He would be facing long, unending days in the future that would be worse than death. If Biggie killed Bel, he might be able to leave, but would once again endure being imprisoned by the black-robed man. He would experience pain far worse than death.
The sword had now left Bel's hands and was floating between both of them.
