The seventh type of creature for the Dungeon faction will either be troglodytes or dragons. There will be no assassins, and no lizard riders either. I think it will be dragons. Firstly, it has already been said that one side of the game will definitely include them. Secondly, a Dragon Utopia will appear. Who will they fight? The final boss from the original game? That would be too difficult. Therefore, I believe that the champion of the dark elves will be a dragon.
