#1) Once you get past the initial area with the guards and past through the area with the cart and Warehouse Key, you'll come to a long street with more guards. On the right-hand side is a gateway that leads down some stairs and to a chain. Climb this chain and go into the room to find the Rune on a table.
#2) This Rune is located in a safe in Pratchett's house in Drawbridge Way. The combination can be found by going to three paintings in a certain order, and finding the numbers in those paintings. The combination is 473 and the safe is on the top floor.
#3) From #2, go upstairs and onto the roof of Pratchett's house. You'll see a balcony overlooking the waters, so Blink onto it. Inside this building you'll find the next Rune, which is on the Outsider's Shrine.
#4) When you first arrive in the Midrow Substation area, there will be a Rune right in front of you on the table.
#5) The last Rune for this mission is located right next to Sokolov on the table he's working at, so you can't miss it.
