What type of creature results from the union of elves and half-elves?
Last I recall, in 2nd edition elvenness was defined by the 'one-drop' rule, meaning an elf with ANY human ancestors was automatically a half-elf. Cerilian elves are of course somewhat different from the generic elves and so might follow different genealogical rules. Which raises another question: as Cerilian elves are immortal and not just very long-lived, do their half-human children age as fast as generic hybrids?

Finally, several realms in Anuire are ruled by half-elves: Brosengae, Endier, Tuornen, Dhoesone. The setting makes a point of emphasizing the distrust between elves and humans (particularly the expansionist Anuireans) and the prejudice half-elves face, but this doesn't seem to be much of an issue for half-breed regents. How much of an obstacle to Kingship should their heritage be? (particularly Dhoesone, some of whose subjects have lost family members to the resurgent Gheallie Sidhe)
