Hmmm... I wonder where that bread really went.
Assuming this is part of the lizardon race idea,
So there are gnomes, lizardons, what else? I think it would be cool if the gnomes were sort of "magical gnomes" and there magic was abused in the railroad construction to help move things and build things. Lizardons (I think that's how Vladimir spelled it) are either tough and bulky or agile and petite, depending on which direction you go. Do you have other races set as well? Perhaps a volcanic environment based race would be suitable. The caves throughout the map are lava tunnels that are now dried up, and are now inhabited by the Lizardons. The humans enslaved the gnomes (gnomes hate humans). The Lizardons settled in the volcanic based race territory (Volcanic based race hates Lizardons). Just an idea for conflict.
Are we also including the Zorbi race?
