Giant, Fire
In ages past, giants mingled more freely with smaller humanoids. Today, the evidence of such relationships is rare at best. Characters with fire giant bloodlines may be the result of voluntary or involuntary breeding with the greatfolk. In any event, characters bearing giant bloodlines tend to be massive for their race, and often share characteristics (skin and hair color, attitudes, and such) with their ancestor.
