The Dragon was added in Eon Production's 6th expansion. It is Lucre-dependent and should not be used in a game without Lucre.
You have the power of treasure. Whenever another player spends Lucre, you get one Lucre from each purchase, with the rest going to the bank.
The overpowering greed of the once-comely race of Dragons has gradually misshapen them in the same way as it has the Assessor race. They have turned the natural wealth of their home worlds into an interstellar investment empire and now seek only to increase their treasure and glory in the profits they steal from others.
