Memphites Barracks
A large garrison in Memphis
Enter the garrison through the north door. There's a single guard you can whistle-lure to his doom.
Getting him out of the way gives you a straight shot to the commander's desk. Luckily for you, it faces south.
Assassinate the commander, and loot the first location treasure from his desk.
Lure in the doorway guard, if he isn't already suspicious, and take him out as well. From here on out, the important thing to note is that few of the 'walls' here actually reach the ceiling. Use them to get a drop an pretty much anyone who crosses your path.
Head south then east, to find a hole in the wall to allow easy passage.
Take out targets of opportunity, then shimmy up the ladder on the south side of the captain's building here.
Patrols come and go here. When they're doing the latter, shimmy back down to execute the captain.
The last location treasure is inside the captain's quarters- red chest in the corner.
Claiming it completes the location.
