Occasionally, I just trip across a cover while browsing the Internet, and I remember it vaguely from my childhood. Magik, the Storm and Illyana Rasputin mini-series from 1984, fills in the space between panels of Uncanny X-Men #160. In that issue, the X-Men, and Colossus's little sister Illyana are transported to the other-dimensional domain of Belasco, a one-armed sorcerer that had previously faced off against Ka-Zar and Shanna, the She-Devil. Near the end, as the X-Men are escaping, Belasco takes Illyana from their grasp. For a brief second, Kitty Pryde loses her grip on Illyana, but regains it, only to pull her through after she's been in Belasco's realm for several years. Later on, Illyana would exhibit mutant abilities to travel through space and time using "discs" similar to those that randomly appeared in Belasco's realm. She also began using magical abilities and summoning a "soul-sword" that went from looking like a lightsaber to a traditional, albeit glowing sword. This series explained what happened in that span of time.
