The Assassins Guild was an ancient order formed by the X-Ternal.
History[]
For 300 years, the Assassins Guild and the Thieves Guild paid tithes to X-Ternal every 10 years in exchange for power and protection. When Gambit was a young man, he witnessed the murder of the Thieves Guild's chosen one for not delivering the tithe in a timely manner. His brother was the appointed as the next chosen one. Shortly following this event, Gambit left the Guilds, New Orleans, and his bride. Ten years later, the Assassins Guild kidnapped Bobby and stole the tithe on the day of the tithe, promising to trade both for Gambit himself. Upon trading Bobby and the tithe for Gambit, Belle gave the Thieves a fake tithe, ensuring their destruction at the hands of the X-Ternal. Fortunately for Gambit, the rest of the X-Men follow him and with Gambit's help they successfully confront the Assassins at the designated place and time and expose their deception. When the X-Ternal came, Jean Grey forced a telepathic link with her, forcing her to see the truth. Realizing that she had been duped, the X-Ternal took away Belle's powers.
