Well, in each village/tribe, there are different Elder Dragons to be found locally. For example, the Elder Dragons in 3rd Gen are a lot more "mighty" (Alatreon, Ceadeus, Jhen Mohran, Guran-Miraosu, Amatsu) than most of the ones found in 2nd Gen (Kushala, Chameleos, Lunastra, Teostra).

Elder Dragons, as a group, are creatures that can live a very long time and can create natural disasters.
