Norn touched the altar, and a small, holographic keypad appeared with symbols that Ryūko couldn't understand. Mikihara tapped a code in, and the top of the altar split open, revealing several small devices. Each was slightly larger than a credit card, and colored a flat gunmetal gray. "These are for you," said Norn. "They will be necessary for your journey, and will help your Digimon attain new forms and strength through Digivolution." "... Digi-what now?" asked Ryūko. "Oh, right. I forgot, your universe has not had any contact with Digimon, either as something real or in media." "'Our uni--'?" Norn abruptly cut her off. "You see, Digimon attain stronger forms when paired with a human Tamer thanks to the Tamer's emotions. In the case of Tamer-bound Digimon, the Digivolution is not permanent. When too much energy has been expended, the Digimon will revert to its normal form, or even a form that it previously had, if so much was used up that they are unable to maintain their usual form." Ryūko took one of the devices. "These are called D-Terminals. While I do not know which Digimon Yggdrasill has paired you with, I have been assured that they are in Nyttliv as we speak." Ryūko frowned. "Wait, as a fragment of Yggdrasil, shouldn't you know what he... it's thinking?" "I am an independently-operating fragment. Let me put it this way: if I were a computer program, I could see something occurring as the computer runs, and decide on my own whether or not to do something. For example, if Yggdrasill told me to take two steps to the right, I could instead take two steps to the left. In that respect, as long as Yggdrasill does not die, then I can operate as I see fit, unless he stops me."
