Infiltration ( Skyrim ) Infiltration is a quest available in . Objectives . Begins at a campsite a short distance east of Treva ' s Watch by talking to Stalleo . It is possible to enter the fort by simply jumping on the rocks it is built into , without having to start the quest to enter the fort and kill the bandits within . However , this does not affect the quest and it can still be accepted . In other words , bandits located inside the fort have no connection to the quest and the quest can still be completed after Treva ' s Watch has been cleared . Walkthrough . Upon receiving the quest from Stalleo , the Dragonborn will be asked to enter the escape tunnel . When inside , there is a staircase with three bandits stationed at the top and a fourth to the right . The quickest way to kill these is to use the Unrelenting Force shout on the three enemies at the top of the staircase into an explosive pot hanging from the ceiling . This will spread oil all over the floor at the top of the stairs , and the Dragonborn simply sets fire to the oil , thus making the bandits catch fire . Note that there is an area to the right of the stairs with two chests . Continue following the tunnel and be wary of the bear trap awaiting upon leaving the area just fought in . After climbing another flight of stairs , the Dragonborn will find a bandit hammering away at an anvil . If the Dragonborn is of a high enough level , he or she should sneak up on the bandit and backstab him ( which should result in a one hit kill ) . If interested in smithing , note that there are iron ingots directly opposite the anvil . In the other room in this area , there are two dead Nords and an Imperial Soldier . As an aside ; they are suspected to be Stalleo ' s family but this is never confirmed . After completing the quest , Stalleo asks " Did you see my family inside ? , " to which the only reply available is " No , I didn ' t . " Stalleo then states that he will take a short respite before continuing " the search . " Enter through the door in the area and continue forwards up yet another staircase . Be wary of the two bear traps directly after entering the new corridor , as activating either trap will alert the two bandits at the top of the stairs . However , if quick enough , the Dragonborn can activate these once again and simply wait for the first bandit to die by standing on them . Quickly kill the second bandit and continue on . The next area is full of bandits ( seven to be exact ) which includes the bandit chief , who has a battleaxe of some sort . Either try to avoid the chief ' s lunges and make quick work of the other bandits in there before targeting the chief , or kill him first before the other enemies . Once all the bandits have been killed , pick the lock of the door ( adept ) in front of the sleeping quarters and search the chest in there . After this , follow the tunnel around once more . Note that there is a bookshelf of various weapons and armor before turning right in the tunnel . After turning right , enter the room on the left to find a Bound Sword spell tome . Head through the dining area and follow the tunnel around to a closed wooden door . Open it and turn left . Be wary of the trap on the floor that activates a spike filled gate to swing round the corner . Once again , follow the tunnel and one will soon come to a large staircase to the right and another tunnel that continues onwards . The Dragonborn can either take the forward tunnel and clear out the dungeon to the left before taking the staircase to avoid being attacked from behind or just climb the staircase killing the enemies along the way and search the room at the top to find a Courage spell tome and a Twin Secrets skill book . Whichever method chosen , the tunnel leads to the way out . However , before exiting to Skyrim , note that there is a chest at the far end of this tunnel but be wary of two traps along the way . Depending on whether or not the Dragonborn has cleared out the fort before activating the quest , he or she will either have several enemies to kill or he or she will simply just be able to activate the lever directly in front when leaving the tunnels . Bear in mind that it is possible to still activate the lever to open the gate regardless of whether there are enemies or not , after which Stalleo and his bodyguards will render aid in fighting the bandits . To complete the quest , talk to Stalleo in the courtyard and receive a Detect Life spell tome as a reward .
