Legion had made a little mistake in his incantation. Instead of the incantation to summon an object from the future, he'd accidentally read the incantation to summon a random sentient being from the future! He blamed the book. The text was so small and squiggly, and you could hardly read the incantation anyways. And everything was all mushed together and it looked the same! He flailed away from the expanding magical portal to the opposite side of his basement, not sure what would be coming out and trying to prepare himself to defend against whatever it was. He would have just stopped time around the portal and figured it out from there, but that spell took SO LONG and there was a coffee stain on that particular incantation, and it was so hard to read... The portal flashed, causing him to jump. He took cover behind a couch, hoping maybe that would give him some sort of cover. The portal flashed again and then once more, the final time being far brighter than the first two. Legion covered his eyes, and thus missed the portal disappearing, and a very confused being that had, before being snatched from its own time, been simply minding its own business, taking its place.
