A danger equivalent to 1000 archdevils... and many other kinds of evil... Are you ready to accept my help?

Thank you for your loyalty to the empire. I am ready to accept your help. I hereby declare you a knight of the empire. Here is a healing potion. And I need your help. Meanwhile, the Gates to Shio are opening again; I close them with my staff. You must help us in battle. Lead a squad of armored knights. You must push the demons away from the gates to the fortress. Distract them. And while you do, we will strike them from the flanks and close the gates to the city.
