After sealing Merlin away, life on this new planet seemed to resume as normal. That was until one day, the sky went grey, and a portal opened up from an unknown world. From the portal emerged twin serpents. They had sharp teeth, and had unpredictable movements. Morgana did her best to put up a fight with them, but they bit her and injected venom into her system. Morgana was weakened, and the only thing she could think to do was seal them away. She gathered her remaining strength and sealed them away in the depths of the planet. Over time, the venom in Morgana's body slowly weakened her, and it would kill her if she had not cured it. But there was no cure, as the venom came from beings from an unknown world. Instead of letting the venom kill her off, she cast a spell that would essentially "kill" her, and turn her into a spirit to roam the afterlife, but the spell will wear off once the time is right.
