After switching places with Captain Britain, Rachel spent two thousand years trapped in the time-stream before breaking free. There she would find an Apocalypse controlled planet where mutants ruled supreme and violently. After a failed attempt to take down Apocalypse by herself, she set about gathering others in her cause. She calls her group 'Askani', which translates into 'Outsiders'. The closest she could come to X-Men. For two years Rachel and her followers stage disruptions and anything else that would interrupt the normal flow. After the defeat of Prelate Diamanda Nero, the Askani gained prominance.
From then on Clan Askani grew into a telepathic sisterhood, religion, armed group with the simple saying "What is... is", guiding them. They prepared for the day when the child who would end Apocalypse's reign would arrive. Their numbers would rise and fall, but that is another tale. And it belongs to the Chosen One, Cable.
