Angel Falls
From Jenny Everywhere Wiki
Angel Falls was an American coastal city in Reality Z-25 31-H. It was protected by a superhero team known as the Guardians, and was also home to the lawful vampire nightclub known as the Bleeding Rose.
Six months after she first became possessed by the Symbiote, Kate Five felt herself drawn to Angel Falls. This would prove an unfelicitous hunch as she was drawn into battle by Guardian Ms. Blitzen, who managed to separate part of the Symbiote from her, although she prevailed against her in the end.
