Good, you’ve got the pattern. Move in when the eastern guard changes shift, they’re the weak link. Use the service tunnel—short, dusty, no patrols. Bring a mirror to glance over the wall, a small cloak to blend with maintenance gear. Keep your voice low, speak the same language as the sentries. Once inside, map the key rooms, note the guard routes, and leave through the same tunnel before the next shift. Stick to the plan and you’ll return without a trace.
