Nooooooooooo!! Someone took TC before me >_<. And this game was pseudo my idea too! Alright, so the reason for dragons was obviously as Cainehill said. Thematic and nifty for roleplaying purposes. However, I am aware it gives some races a nice bless advantage so I was open to setting ideas and also how we can work around that. (Perhaps, no paths' greater than 8?)
Yeah a second council of Wyrms might no be a terrible idea come to think of it. Dragons do give bless an advantage. Or perhaps allow size 6 fliers and call it council of the Bygones.
