Hic Sunt Dracones
Orcs: the Untouchables
Orcs are the newest Race in Terra Antiqua, deported from their Homeland (a.k.a. The Savage Land, the New World or Terra Incognita) to become slaves or soldiers for the Nobility (and their new ally, the Dwarves). Unfortunately Orcs are infected with the most virulent pest, the Orc Plague, that attacked plants, animals and humans of Terra Antiqua, deforming and eventually killing them. Therefore Orcs were immediately released, and now they ravage a Land which they don't belong, hunted down by Peasants and feared by all.
At the time of the Deportations, slave traders used to drown Females and Elders in the Ocean when they were getting short of supplies. Female Orcs are nowadays extremely rare, and Shamans rarest. Orc lost most of their traditional culture, but not their lust: Orc mated (mostly through rape) with human a new race, the Half Orcs.
Elves are immune to the Orc Plague, so it is quite common to see Orc Communities in the Freeholds, or Orc working on a Flying Ship.
