I'm just a little confused...If the sun and moon curse doesn't exist then why are vampiros weakened por the sun and hombres lobo bound por the moon...is it because of the curse on Klaus? Please Enlighten Me...Thanks :)

Remember when Elijah was telling Elena that every creature has a weakness. And that is because it brings balance? Well, vampiros are weakened por the sun and hombres lobo are bound por the moon because that is their weakness. No curse involved.

So, the sun and the moon curse doesn't exist, yes. That was made up por Klaus and Elijah eons ago. The real curse is the curse on Klaus. That is because he is a hybrid. The werewolf part of him remains dormant because of spells that were cast upon him. No one believed someone should possess that much power.

Hopefully I explained clearly? :)

Its the witch's way of keeping balance
