The Parliament of Hours
The world of Aschevon has a broad expanse of races. In game terms, any race from the D&D 4E supplements can be played in this setting.
Deva are said to be eternally-reincarnating souls that were formerly the servitors of the gods. Most Deva hail from Nideharab, but due to their process of metempsychosis (reincarnation), they can appear in any region of the world, and integrate themselves with any culture.
Doppelgangers, otherwise known as Changelings, are capable of changing their appearance at will, and as such it is difficult to determine how established their race is within any culture.
Dragonborn are somewhat establised within the State Isles, and they are not uncommon in the city of Montmarais.
Drow are established within all lands in the former Capetian Empire, including Montmarais. They are typically associated with old Imperialist leanings and the aristocracy.
