The Halloween Warriors [EPUB ebook] 
Legacy and Adventures

On this occasion, Matilda, resentful of her constant setbacks, decides to change the course of history, then goes back to the time when she was still friends with Gellfara. To ensure her victory, Matilda made Gellfara disappear from history so that he could never create the Halloween warriors. Even so, Matilda achieves temporary victories that she cannot retain for long; but in the end, she ends up allying herself with the cult of the demons of the galaxies. Dorian grants a cult for herself. Since then, Matilda and Dorian remain in the galaxies but turn the sinister cult of Matilda on earth into a training base for the demons of the galaxies.
