People have wondered why it is exactly Divinity II goes by the name of
Ego Draconis, so let me explain. "Ego" is Latin for "I" and "Draconis" is the genitive of "Draco" meaning "dragon". Why then, isn't the game simply called "Ego Draco"? Well actually, there is a very good reason, namely that "Ego Draconis" is a
genitive of origin. This means that Divinity II isn't called "I, dragon", but "I of dragon", or more fluently translated, "I, descendant, scion, heir or successor of the dragon". Which of these possibilities comes closest to the meaning we want it to carry, or how it ties in with the story, is for you to find out when the game ships.
Hope this clears things up! Class dismissed.
