The Messenger
The player character of Blood Message is a nameless messenger. He has been entrusted with a critical message that must reach Chang'an, the capital of the Tang Empire, during the Shazhou Uprising of 848 A.D.
Role
The messenger is not a soldier by trade and not a hero in the genre-conventional sense. He is a man with a job, a son, and a long road ahead of him. That framing shapes the gameplay: he fights when he has to, hides when he can, and picks his paths carefully because a messenger who dies alone in the desert does not deliver anything.
With His Son
He is travelling with his young son. The son is the reason the father's choices carry weight, and the reason the campaign's themes of sacrifice and family land at all.
