Amazons

Racial Power
From the base game, Amazons get 4 extra Race tokens for Conquest only. At the Redeployment phase, remove 4 tokens from the map, abandoning regions if nessecary. Next turn, the 4 tokens are used for conquest again.

Amazons get 6 tokens normally.

There are 15 Amazons in the box.

Trivia
The Amazons are the only exclusively female race in the base game. After many comments about this, Days of Wonder promised to address the issue, making an all-female expansion: Grand Dames.

Of course, one can suspect that Sorcerers have their Sorceresses, Halflings their better halves, etc. It was simply the archetypical male representatives that were selected.
