No POI for Zek, The Scourge Wastes
 

I hope someone can help me with this...I have no POIs on my map for Zek, The Scourge Waste. I have tried both solo and heroic. I have POIs for Zek, The Orchish Waste but nothing for Scourge. It does allow me to put in my own POIs but since I don't know where anything is it isn't very useful. Can anyone help?
Thanks
