The haughty celestial elf
According to Azzy's knowledge, the Elf race went extinct long ago. The Supreme Commander of WAMO is known to the world as the last remaining elf. From the Reaper, Azzy got to learn that Louis was also an elf. That makes only two of them.
It is why an appearance of an elf at the clan greatly shocked him. However, it appeared that the guest wasn't pleased by his reaction.
The 6-foot fair-skinned elf with a slender build, violet eyes, and silver hair, spoke in an aloof tone, "I'm not an elf, human… I'm a Celestial elf, the tribe with the highest standing even among the high elves (royalty)."
The strikingly handsome-looking guy (both from human and elf standards) spoke to Azzy in a tone as if he was scolding him for being disrespectful by addressing him as a mere elf.
Azzy read about the elf tribes, recorded in the Book of Death.
