After Lancelot brought the knights who had found the cursed object to Daniel, it became clear that the curse had affected them. Signs of rotting were visible on their bodies. Still, fortunately, Arthur had informed Daniel in time, preventing the worst from happening. Such as his entire knight corps turning into the living dead without his knowledge.
Daniel led the cursed knights out into the open and used a spell card to destroy the curse within their bodies. Once the curse was eradicated, the knights began to heal. Those more severely affected, such as the ones who had directly touched the cursed object, were healed personally by Daniel.
The knights, grateful to the wizard, also thanked Arthur for calling Merlin to address their situation.
