The story has a new name: The Legend of Caius Wintermasus
At the begining narrator says: “You think you know? I will tell you the true story now.”
Wintermasus becomes the sex slave of Arminia, gets to know the forthcoming attack and wants to warn the legions.
“Since Wintermasus was no longer allowed to speak, but only to bark, the true course of events has been kept secret to this day. And now you know the true story.”
