"Cave Entry" 1&2 are the entries to the tunnel under the glacier that join Ocean's Last Breath to Quickwood Coast. The excavated cave isn't on this map.

I hate to spoil all your work, it's a great map, but Greywing Cove is in the wrong place. I'm not sure you can change it now. It's actually between Old Lyndow and the Seltspring Coast. It's tiny and can only be reached by boat. It's marked by the only Blushwood trees in the area that are on high rocks or narrow islands. About 3 or 4 of these steep islands block the tiny beach.

What is "Cave Entry 2"?

nice map!
