Half-elves, as their name implies, are the offspring of humans and elves. Half-elves are a subrace unto themselves, blending the features of human and elf. Half-elves look like elves to humans and like humans to elves (hence their elven description as "half-human"). They do well with elves, humans, gnomes, dwarves, and halflings, a social ease reflected in racial bonuses to the Diplomacy and Gather Information skills. In the case of conflicts between elves and humans, however, each side suspects a half-elf mediator of favoring the other. The drow despise them, referring to them as 'Mongrel half breeds'. The main character of the initial Dragonlance series, Tanis Half-Elven, is a half-elf, as his name implies. In the Dungeons & Dragons Eberron campaign setting, half-elves consider themselves a separate people from humans and elves both and "breed true"; they bear the dragonmarks of Storm and Detection. Half-Elves have curiosity and ambitions like humans but they have sense for magic and love for nature like their elven parents. Their skin is paler than human skin and they are taller and bigger than elves. Half-Elves have long ears like elves. They live about 180 years. References
