You can only imagine how awesome this area must have been when the Only Old One ruled from his palace.
A truly golden age for the Holy Country before the Pharaoh swam ashore and ruined everything. (Was it the Holy Country before Belintar?) Well not quite. The Only Old One was never really what he used to be by the Second Age, and by the early Third Age, he was clearly failing and had lost the mandate of Hell.
Also what really comes out is how densely settled Esrolia is. A settlement every 4 or 5 km.
