I was outside BWD flying around waiting on my raid to start and I noticed a red spot over in a corner. Its a tiny hole that goes underneath the map. I was with a couple people but they couldn't fit through the hole tho I could. So I assume you have to be human or gnome or something small to get through it.
Here is a SS of where it is at. I have not had time to go very far to see if there is anything because my raid started.
