Nightcrawler's mother, Irene Adler, is a long-lived mutant with the gift of precognition. Decades ago, a sudden surge in her powers revealed nearly everything that would unfold in the years ahead. After that rush of visions, however, her eyesight began to fail. Before she went completely blind, she recorded everything she had seen in a diary. To keep its prophecies from falling into the wrong hands that would threaten mutantkind's survival, she concealed their true meaning in cryptic words, hoping that the right person would one day unravel her riddles. At the furthest edge of her vision lay an Incursion that would destroy both Earth and another world. And her son, Nightcrawler, was the only one who stood any chance of averting the catastrophe.
