Several... altercations? later, you get through the several rings of sentries. They are, uniformly, unhappy to be dealing with outsiders. However, though they are dismissive of Felix, they do allow you entry to the camp. Finally, you stand before the Praetor's tent.
You are kept waiting for several minutes while Felix is brought inside. You hear indistinct voices within - Felix's pleading, and another, firmer voice clearly expressing displeasure. While that is going on, a ring of knights wearing modified Roman armour keep their unhappy eyes on you. You feel more like prisoners than emissaries. They do not even offer you chairs, refreshment, or water to wash with.
At length, the Paetor emerges. Heraut de Aprés is, to all appearances, Roman. The short cropped yellow hair, the colour of his skin - even the hawkish nose. His face clearly shows impatience. He is dressed in the roman fashion, with a bronze breast plate, leather skirt studded with disks, and a broad short sword on his hip.
Felix is behind him, being dragged by two knights. As soon as they emerge, Felix is led a short distance away out of sight behind the tent.
Heraut looks you over, clearly unimpressed. "I presume you have some documentation?"
You hand over Uther's letter.
"Your credentials appear to support your claim.
You hear the distant crack of a whip, and Felix cries out in pain.
Heraut nods, and a servant scurries forward with a fine chair. He takes a seat.
"Why have you disturbed me on campaign?"
The whip cracks again, and Felix cries out. He is somewhere behind the king's tent.
