Wait that means after they poisoned/killed the mc’s mom somehow she transported her baby to the past and croaked. Then the Black Forest was created and the mc’s dad preserved her body in the black forest… I feel like him doing that is what is keeping the fairy forest from being fully exposed but it’s also allowing them to be corrupted.
How does that mean he helped capture fairies? He only tried to kill that one fairy for trying to take his daughter. Connect the dots or perish neow!! (I believed the mc’s mom was the previous fairy queen)

ohh it's turn out basilan was the on who help holy king capture fairies
