If you look closely at the residents of Tailfeather, they all have sharp clawlike fingernails, even on the ones that wear normally-unclawed gloves. Even the skywatcher has claws.

Is there a reason for this? Is it ever explained? Is it a dragon thing? A chocobo thing? Are they werewolves? Or is it just meant to indicate that hunters have poor nail care?

Me and my friends have been wondering about this for months.
