This is my first time playing the game and I'm supposed to locate Sir Brash by following a trail of bodies, but I can't locate him for the life of me. I've been to each area of the map a million times at this point and am going slightly batty here. Can anyone point me in the right direction please?

If you go to the east map with the straying Mermaid  and then go north to the next map there is a dungeon to the Northwest part of the map in is where you will find Brash .

Thanks, I found a blood stain on the ground I had previously missed, in the area you mentioned. I'm a bit colourblind, so I have trouble with reds and greens sometimes.

np happy I could help ya
