Classical Tiefling

Classical Tieflings are Tieflings who were born through hereditary means, rather than through magical exposure. Due to the general rarity of same-species Tiefling couples, they are far rarer than Environs Tieflings.
A major bloodline of Classical Tiefling is that of House Althis, of whom Calypso Althis-Ermendrud is their most famous member.
