Welcomed to Mizahar!
You can live almost anywhere, really. Read the cities lore and find one you would like to roleplay in. The lore and the Player Guides in the cities forums will usually tell you which races are accepted within a city. If you're still in doubt if a mixed blood can live in the city, just PM one of the city storytellers. But most accept mixed bloods, although they can be treated differently.
If you have questions though, please ask them on the
Questions and Answers forum.
