Origin Sage Joining the Hellfire Club Teresia Karisik was raised in a war-torn country in the Balkan region of South-Eastern Europe (likely Bosnia due to her surname). In her teenage years Teresia had fled to Afghanistan, which was under invasion from the Russians, which forced her to learn how to use weapons and fight against soldiers and local bandits. One day, she felt compelled to enter a local cave and found Professor Charles Xavier trapped under some rocks, his legs crushed. Soon after, some bandits who had raped and killed a convoy of U.N. workers attacked them, but Tessa drove them off, killing one of them. Some time later, Professor X recruited her into the X-Men, but kept her secret so she could use her telepathic power to spy for his fight for peaceful co-existence between mutants and humans. Tessa’s first mission was to infiltrate the Hellfire Club and become Sebastian Shaw’s adviser. Shaw even kept her after his leadership, due to her usefulness of keeping large amounts of information.
