I Love You
There was nothing left to be taken care of so they all returned to the academy to make final preparations. Alex didn't have much information about the dimension he was supposed to go conquer, he had no idea what was the current state of the war there between his army and between the locals of the dimension, and because of that he was unable to determine what sort of supplies to take along.
But he had a few plane keys and the blueprints for making one, while it was not as permanent as a planetarium, it was the only available option for him as the planetarium on the Morgana only had one location on it, and that was earth. He would be able to register a new location once he gets to the dimension, but even then, the Morgana wasn't strong enough yet to make trips across dimensions, he had to at least improve on its flaws and wait for its consciousness to awaken that way a high degree of accuracy could be achieved when travel between dimensions was required.
