Discussion of the Necropolis faction.

I certainly won't argue with someone with such an avatar, but didn't dragons appear in the early era? If not, then in which era, and provide evidence.

There were dragon-gods, and the ones in the Elven castles of Heroes of Might and Magic V are their descendants, who have lost their immortality and power. This was in the lore of the fifth game. Perhaps they haven't been tamed yet.
