A Reign of Toads
Blood of Old Valyria
Valyrian features include pale skin, delicate frames, Caucasian features and peculiar golden or silver hair. Their most notable feature is also the rarest: vibrant purple or indigo eyes that lend them an otherworldly cast. Despite the fact that Valyria is more or less the equivalent of Rome in the World of Ice and Fire, Valyrians have no real world equivalent, and resonate with a bunch of fantasy tropes that make them feel more alien than most other ethnicities.
The blood of old Valyria refers to people who are ethnically related to the people of the lands of Always Summer. Most such people were Valyrians, though their blood exists in numerous places on both sides of the narrow sea in the world after the Doom. Particularly Volantis, Lys, and the isles in Blackwater Bay people with Valyrian features are more plentiful, though always a rarity.
