Date April 2006
Writer(s) Andersen Gabrych
Artist(s) Pop Mhan, Jesse Delperdang, Adam Dekraker
storyline Cassandra didn't want to believe she was dead - Bludhaven needed her. Stephanie showed her Bludhaven had been destroyed. She then burst through the fluids of the Lazarus Pit. Shiva had brought her back.
Shiva told her daughter how only after Cain had killed her sister did she realize how much she'd been held back. After their daughter was born, she left and became Shiva.
They fought; Cassandra won. Instead of finishing off her mother, she hung her above the Lazarus Pit, so that when she fell, she fell into it.
