Complex Playable Races - Primer

These races represent races that range from rare to common within the gameplay space, but come with added chanellges to playing them. These challenges could be in developing a strong enough character background to justify, or challenges in game play usually relating to roleplay and social dynamics. For example, Kenku are common throughout the human empires, but have the unique challenges of strange speech patterns, as well as being a marginalized part of society. Leonin on the other hand, are wanderers from the vast open plains south of Tiriande, so they wouldn't be unheard of in those regions, but very, very rare in most of the rest of the game world.
