Meeting with the Admiral | The Hound Pits Pub #2 Dishonored Guide
Last update: 11 May 2016
New Main Quest: Speak to Admiral Havelock in the bar
New Optional Quest: Use the Heart to find the Rune near the Hound Pits Pub
I recommend that you deal with the optional quest first. Leave the pub and return to the docks. From your inventory, select the heart and use it to find the rune. Thanks to this you will determine that it is located on one of the islets.
Depending on your preference, you may teleport from one islet over to another using Blink or reach them swimming. In the case of the latter, however, you need to watch out for piranhas. You may kill the fishes (using gun for example), or avoid them by swimming shorter distances. Locate the islet with the rune on it (the above screenshot) and collect it. Caution - you do not have to use up the rune right away to acquire another one of the powers. You may keep it, thus starting a collection of runes required for unlocking better powers
You may now return to the pub and go to pub's main room to meet admiral Havelock. Approach him and listen to briefing that he gives you. During the briefing you will learn that your first task will be to murder Campbell the Overseer.
