Dishonored?

Date: 12/17/2016

I was at my house but I had Corvo Attano's powers from Dishonored (the game) and I held the heart and it said that there was a rune nearby. So i went outside and went around my house, there was a grated hatch on the ground and I opened it and dropped down. Inside I was greeted by a seemingly dead mermaid who was very pretty, some slaughterfish and a rune behind some bars. The mermaid ask's for some food so I blink to the rune, kill a slaughterfish and give it to her. Then a little puppy comes in and the mermaid tells me that it's hers and that she wasn't always a mermaid trapped in the sewers. her sister (I think) had turned her into a mermaid and trapped her down there, now the mermaid wants me to assassinate her sister. (again I think it's her sister) I leave the sewer and walk to a building, I blink up the building while hiding from windows and I see my target. I blink to the targets window grab her and throw her off the building. Mission Passed?
