In my (PbP) campaign, players can choose Afridhi and Skandaharians (from Blackmoor) as playing characters as well and I have write ups for that. Hopefully later on, when I'll be home, I'll remember to copy and paste them.
In alternative, you can join the game (viewtopic.php?f=24&t=18973
The Afridhi are a dark-skinned people with flaming red hair. They are slightly shorter than other humans, only 5 feet on average, but make up for their vertical shortcomings with great physical power.
The Afridhi are a frightening race of humans who hail from the most inhospitable parts of the Goblin Kush Mountains. Powerful warriors, the Afridhi have survived
for centuries in these cold mountains by force of will and discipline.
During last few generations, the Afridhi expanded their lands far away from the Goblin Kush, fuelled by rising religious fundamentalism linked to the monotheistic cult of Zugzul. During the rise of fundamentalism among the Afridhi, all of them not feeling enthusiastic about it had to run away to avoid being either killed or enslaved. Some of them escaped to the Duchy of Ten and to Blackmoor and settled down in quiet places, away from the limelight and trying hard not to be confused with the Afridhi worshipping Zugzul, for example wearing different clothes from usual Afridhi ones, with Zugzul symbols laced all over. While they have lots of issues with racism, they are now not too different from all other inhabitants of Blackmoor, apart from the fact that they are all atheists (and therefore they can't have Priestly Powers), as a reaction to the fundamentalism they had to run away from, but being an atheist is usually not an issue in Blackmoor.
Skandaharians are a race of tall, pale-skinned, blue-eyed, blond-haired sea rovers. From their secret homes in the frozen north, they sail in long ships to raid the coasts of the Thonian Empire. In more recent years, they have concentrated on Blackmoor instead, which they unsuccessfully tried to invade during Blackmoor’s rebellion against the empire. Many Skandaharian warriors died in that fiasco, and many barbarian raiders carry a burning hatred of Blackmoor because of their humiliating defeat. However, other Skandaharians and their descendents settled in quieter parts of Blackmoor (very often near the coast) and started a new life in the Kingdom.
Skandaharians are often noted for their greed, destructiveness, and cruelty... in this regard, they are often compared unfavorably with orcs. However, Skandaharians hailing from Blackmoor are not that different from other citizens.
