The Land of Aelia
The sons and daughters of angles, Aasimar are uncommon in the world of Aelia, but not so uncommon as to be characterized. They are even less common than teiflings, mostly due to the nature of how each "mate" with humans. Angles tend to only take on a human lovers when they are ordered to by their Patron Gods, or they are overcome with true romance.
Aasimar are very rarely unwelcome anywhere. Oppius Aasimar are likely to rise high in the clergy. Anywhere else, they are an oddity, and are more effected by their parentages' reason for procreation than how society anywhere sees them.
