1 hex = 5 miles
SW (bottom left) corner is the city of Leopard Bay.
East from there is the Four-falls River emptying into the Coral Sea.
The river climbs up the mountainside to the 3000’ elevation point you are now at.
The dwarves fill in the path north to Cadensong/Jullal’du’at — a 50 mile trip (sorry my guess of 20 was a little off).
The lake is unnamed.
With the Dragon Empire lift activated, your horses at the bottom of The Well can easily be recovered.
