Headscratchers / Ancient Domains of Mystery

• Why does the "very light" corruption decrease Appearance? Its other bonuses and penalties (decrease in Strength and Toughness, increase in Dexterity and Speed) all fit pretty well, but I don't see why it would make you uglier to suddenly become very light.
  • It reduces the PC's weight to one-tenth its normal value. This isn't a matter of "They look like they need a good meal," it's, "Oh, crap, that desiccated skeleton is a living creature!" You're so thin you should have died from starvation long ago—but somehow, you didn't. Very creepy.
  • Maybe it gives you a gaunt/starved appearance. Or "Uh-Oh" Eyes. Or a moustache on a woman.
  • Perhaps it results in an Uncanny Valley effect as your movements look off because of a lack of inertia.
