Halflings live in South America. Spanish colonies are rampant throughout the continent but the Halfling communities are far more aggressive towards reclaiming their lands by poltics and by blade. Halfling cities in the North are receptive to commerce, trade, and work well with the other nations. Thos in the middle cling to the forests and have a deep connection to nature. Those in the South are isolationists and have begun using ancient ruins to progress tehir study of magic.
Halflings are the same as in the SRD. THey use the same aging table or human times 1.2.
