While Emma Frost was laying in a comatose state, the Dr. John Sublime harvested eggs from her to begin experimentation. The Weapon Plus program began the cloning to develop a powerful weapon capable of killing every mutant on Earth by combining their telepathic abilities. The project was designated Weapon XIV, and girls were incubated and artificially aged inside the subterranean level of The World.[2] Thousands of girls were cloned from the ovum, but while the other remained dormant, five girls were sent to infiltrate the Xavier Institute as students and sisters, in order to hone their talents for Sublime's purposed.[3][4]
