Tales from Elrond
Due to their heritage to a savage, pillaging and destructive species that is a menace to many civilizations, the Half-Orc is rare in civilized society with only Aasimar being more rare. Most Half-Orcs are the offspring of forced reunions between Orcs and humans, but occasionally these unions are consensual.
Most Half-Orcs live in Orc tribes where they find in easier (though they still have to work twice as hard to prove themselves because of their mixed heritage) to find acceptance. Those that seek to socialize with the other civilized races face mistrust, suspicion and hostility. Their heritage hurts them but also helps them as many people recognize the potential as Half-Orcs to be fierce fighters and seek to utilize them as caravan guards and body guards and the martial fields is where most Half-Orcs can be found.
