Unique technologies

Main article: Unique technology

While all other technologies are available to multiple different or even all civilizations, unique technologies are only available to one single civilization. They were introduced in The Conquerors, where every civilization got one (two for the Goths) unique technology that was available for research at the Castle in the Imperial Age. The Forgotten gave every civilization a second unique technology so that every civilization now has one in the Castle Age and one in the Imperial Age.
