Nightfall was a Dreadwalker from Fogshadow Tower, a mysterious fortress in the middle of the Poison Sea.
While most Dreadwalkers stayed within the noxious cloud they called home, Nightfall preferred to delve into the black abyss and hunt the dark monsters that threatened her people.
One day, while exploring a deep cavern in her submarine, the Sea Shadow, Nightfall came across a huge object that pulsated with a strange energy. It was gigantic, and before she could realize what she was looking at, it hatched! Out came a creature 100 times larger than anything she had ever seen! She fired up the engines and raced back to warn her people.
As the last citizens boarded an evacuation ship, the colossal head of the Leviathan broke the surface of the water and let out a terrible roar! Without hesitation, Nightfall rushed towards the monster, blasting it with everything she had while the others fled.
This act of heroism caught the attention of Master Eon, and the rest is Skylander history!
