Madame Sanctity's History
Tanya Trask was the daughter of Dr. Bolivar Trask, the creator of the original Sentinels. Tanya and her younger brother Larry Trask were both mutants. Tanya's time travel powers caused her to "disappear" one day.
Tanya ended up over 3000 years in the future where Apocalypse had ascended to power a century prior and controlled much of the world. She was found by the Order of Witnesses, a group founded in the late 21st century by a mutant seeking redemption. They named her Sanctity and taught her of the Twelve.Apocalypse sent his High Priestess Diamanda Nero to deal with the Order of Witnesses. Nero captured Diogenes and Squy'rr, torturing them for information and then wiped the the Order. Tanya and the other children protected by the Order were saved by the Clan Askani, a group of rebels led by Rachel Summers who opposed Apocalypse.Tanya learned to control her telepathy and telekinesis directly from Rachel as a member of the Askani. The Askani beliefs taught Tanya such tenets as "what is, is", that fate must be embraced, and "thanks for today, please for tomorrow", a belief that the past brings hope. They preached that the "Sacred Timeline" should be preserved and nurtured through careful time travel. Believers deified the ancient X-Men: "the Xavier" became a father figure, the Bright Lady a mother goddess, and the prophesied "Dayspring" or "Askani'son" their messiah.
As a young woman, Sanctity defied her Askani teaching and tried to change the past so that her father's creations wouldn't destroy mutantkind. She returned to the modern era. Rachel followed her, trying to stop her. She approached her father, but Rachel erased that memory from his mind. Before Rachel returned her to the future, Sanctity uploaded the identities of the Twelve into Master Mold's core programming, hoping that by having the twelve destroyed, she would prevent the rise of Apocalypse. Larry Trask stumbled on evidence of Rachel and Sancity's psychic duel, convincing him that mutants walked among them. This pushed Dr. Trask to complete his project. Sanctity had set in motion the events she had travelled back in time to stop.Becoming Madame Sanctity, Tanya became an Askani high priestess and sent Ch'vayre to the past, to influence Cable into killing Apocalypse in hopes of changing their timeline, visiting him occasionally.Apocalypse had succeeded in wiping-out the Clan Askani and Sanctity fled to Ebonshire and created a small sect called the Askani Sisterhood, who only taught women. One of her disciples was Aliya. After the death of the Mother Askani (Rachel), Sanctity was the most powerful Askani left. However, Tanya's experiences had left her severely traumatized and her sanity was under strain.Tanya was responsible for sending Scott and Jean Grey-Summers to 1859 AD, only telling them to stop a great tragedy, but not specifying. Upon arriving in Victorian England, Scott and Jean found the biologist Dr. Nathaniel Essex and recognized him to become the evil geneticist Mr. Sinister. Sanctity actually had sent the couple to ensure that Dr. Essex became Sinister, as Mr. Sinister was necessary for the birth of Nathan Summers the Askani'son, and to stop En Sabah Nur from conquering England and creating a plague to destroy the weak of the world. After defeating Nur and the.transformation of Mr. Sinister, Sanctity sent the couple back home.On one day, Madame Sanctity sent Aliya to recruit the Askani'son and, after she returned with him, he asked to learn the ways of the Askani. Even though Nathan Dayspring was a man, Sanctity ordered Aliya to instruct him, because he was the Askani'son. After the New Canaanites attacked, Madame Sanctity was seemingly killed, but was actually beamed aboard the New Canaanite's leader Stryfe's ship so she could tutor him. Sensing the similar psi-signature to Nathan, Sanctity agreed.
