In the After Dusk Inn, Nox sits at at table with five other men. He is gambling and drinking but he's sober enough to think properly. The After Dusk Inn is a place for the Last Army soldiers to bet on their deaths and gamble. You walk in and sit at a table in the so he doesn't notice you. After all he's only ever seen you once, at the palace. If he sees you and turns you in you'll be in huge trouble for leaving the palace and not going by King Seryth's rules
