Having a lot of problems finding Cathal the Ranger which I believe is in Farcrag Castle. Exactly where is he? Who is he near? Please help.

Go to the Farcrag Castle leystone, go north (towards the pet vendors) and take the stairs on the right (there will be trees on the platform up the stairs), go through the opening on the left of that platform and head up those stairs. He will be in the room up there!!
