Hey there,
Caer Darrow I believe was the human base on map 4 (i think...), anyway, it was a city north of the river between Lorderon and Azeroth.
(Disclaimer: this is based on a 5 year-old memory)
EDIT: i also think it was conquered by the Orcs also.....
EDIT 2: FORGET THAT! Dun Modr was the river base X_X |
