Lone looks like a ordinary DeathWing, black scales, grey underbelly. His mask looks normal too, a bit chipped, but smooth. His horns are curved, and he's slender and quick, just in case he needs to escape a tight place.
Lone's wings seem to curve downwards, and his talons are sharp. He has a few scars, and if you got close enough to see his eyes, (Very unlikely) they would be amber, His smiles always seem fake, and his wings are slightly ragged, but enough for him to fly.
He gets tired after long flights, and prefers working alone, the day you see him working with others is probably the day you die.
