Octavius watches as Dalia and Silene clear dirt from a forgotten stone door, while avoid the sightlines of bandits in the fort. The fort itself is low quality from design and quality. Octavius observes the guards walking between tower platforms around the fort (white arrows) but never along the wall near Dalia & Silene. The fort is constructed from rough logs and would fall to any real siege, Octavius estimates that a strong warrior could climb over the wall with moderate difficulty. Observing the guards gives Octavius a good sense of patrol rotation, which could help him sneak by undetected.
The dirt is loose and clearing the door only takes Dalia, Silene, and the earthy Filbert 5mins to clear. Dalia and Silene probe the door which could open without fuss. It is heavy though, it would take effort to open without making a loud sound.
OOC:
Give me a stealth roll if you open the trapdoor.
