It is in the area where you found Ruksana's horse. Go along the west side of the map and you will find the entrance.My geographical cretinism is playing tricks on me. I took the Hunt for the Hippogrif quest but can't find the area where the orc camp is supposed to be. I visited the orc camp where Ruksana's quest is completed but nothing happens there. I consulted the walkthrough which suggested heading to the northeast forest and then west. What northeast forest? There's a road from Ly'ras to the area where Ruksana's horse was, then there's the area with Anariel but that's to the west. What gives?
