Eargon Series: setting

Throughout the whole series there has not been one clear out setting but they have been in the same set of land. They have been in Alagasia and it is described as a very old type of place it sounds like a lord of the rings set-up lots of farms, mountains, city's, and caves. He travels all of this land getting in fights with different weird creatures and he is a strong warrior but as the book goes on Alagasia starts to change and it becomes a dark evil place and Eargon is the only hope.
