<span class='standouttext'>Spoiler : </span><span class='spoiler'>Go through the corridor - beware of traps. then you're at a north door, leading to a guard room at 16 => kill them, the lieutenant drops a key. this opens a small lever room in their room at 17 => this lever opens the gap in east at 18.</span>
