Andrew and the former headmasters waited for Dumbledore’s spacecraft to reach outer space, watching an A Legend dream while Headmaster Black relayed updates. Dumbledore began the planned spell experiments, but Andrew and Professor McGonagall warned him not to attempt an unscheduled spacewalk.

• Headmaster Black left his portrait in the hall and traveled to check on Dumbledore, while Andrew summoned the A Legend Dream Orb for the others.
• Headmaster Black returned and reported that Dumbledore’s spacecraft was nearing the edge of the atmosphere and that the view outside had grown dark.
• Dumbledore reached the planned point in outer space and tried to contact Andrew through a Two-Way Mirror, but the image and sound were badly distorted.
• Headmaster Black relayed that Dumbledore could still cast spells and that the auxiliary spacecraft was working, then reported Dumbledore planned to try a spacewalk.
• Andrew forbade Dumbledore from attempting experiments outside the plan, and Professor McGonagall threatened to withhold desserts if he disobeyed.

Andrew monitored Dumbledore’s spaceflight experiment and helped recover him and both spacecraft at sea. Dumbledore returned safely after completing the planned tests, while Andrew set out the work needed before they could attempt a lunar landing.

• Dumbledore reported that he was gazing at the planet and considering casting magic on it, so Andrew warned Headmaster Black to tell him to follow the original plan and return that evening.
• Andrew explained that Dumbledore should land over the sea, where they could slow him down more safely than at Hogwarts.

• Andrew told Dumbledore that more people could travel next time, then reminded him that Professor McGonagall’s sweets ban would begin tomorrow.

Andrew and a group of prominent wizards completed a new spacecraft and prepared to launch their Moon Exploration Plan. They planned to inspect the craft, explore a lunar camp site, and decide whether to recruit more wizards for a future moon base.

• Andrew, Dumbledore, Mr. LeMei, and the other headmasters developed a second-generation Aircraft and made several trips into space.
• The team finished a new two-part Explorer, equipped with a successful Gravity Device, and Mr. LeMei hoped to bring back a piece of the moon.
• Madame Maxime worried about recruitment, while Headmaster Vladislav said Vodka could help persuade people to join.
• Karkaroff supported building an Exploration Camp on the moon and moving advanced classes there, citing the growing reach of Muggle exploration technology.
• Andrew set the launch plan: inspect the Spacecraft the next morning, travel to the moon, and decide afterward whether to recruit more people and expand the project.

Andrew and five other Wizards traveled to the moon aboard Dumbledore’s Aircraft, preparing to explore and establish a base there. They reached the Lunar Surface and flew toward a landing site, where they planned to begin setting up camp.

• Andrew told Hagrid that the group was going to the moon, and Hagrid explained that he was preparing wither skeletons for Dumbledore’s planned lunar base.
• Andrew, Dumbledore, Madame Maxime, Karkaroff, Mr. LeMei, and Vladislav boarded the Aircraft and began their journey after saying goodbye to Professor McGonagall.

• Andrew said they were about half an hour from their destination, and the group prepared the Gravity Alchemy Device before planning to explore and set up camp.

Andrew and the headmasters landed on the moon and began preparing an Exploration Camp. Andrew made stone building materials, while Dumbledore cleared an unexpectedly vast construction site, leaving Mr. LeMei to remind him of their limited supplies and the Gravity Alchemy Device’s limits.

• Andrew and the headmasters landed on the moon and tested magic and speech bubbles for communicating there.
• Dumbledore assigned the headmasters tasks: Andrew would make building materials, Karkaroff would set up anti-detection magic, Madame Maxime would tend magical creatures, and Professor Vladislav would survey the terrain.
• Andrew flew to a nearby crater and used Transfiguration to shape lunar soil and rock into stone blocks, then moved them toward the camp site.
• Andrew noticed Dumbledore was flattening a huge area and wondered why the temporary camp needed so much space.
• Dumbledore praised Andrew’s materials and asked whether he had studied Architectural Magic, while Mr. LeMei reminded him that they were building only an Exploration Camp and had food for three days.

Andrew and the Headmasters returned from the moon after planning an underground Hogwarts branch with a surface Quidditch pitch. Dumbledore proposed openly inviting Wizards to help build it, while Andrew resisted being sent to handle construction and negotiations.

• Andrew persuaded Dumbledore to delay surface construction until they completed Protective Magic, and the Headmasters agreed to build the Quidditch pitch on the surface while placing other facilities where heating and magical support allowed.
• Andrew asked whether a large Floo Network could connect Earth and the moon, and Dumbledore said it seemed possible and noted that some restrictions had weakened.
• The Aircraft plunged into the sea, and Andrew froze himself onto the water, asking the others not to summon him again until the Transportation Device was finished.
• Dumbledore suggested bringing Andrew and Professor McGonagall to help build the moon branch, but Andrew argued that the Dream Mushroom and negotiations still needed his attention.
• Mr. LeMei raised whether to keep the lunar project secret or announce it, and Dumbledore chose to invite Wizards openly while they still controlled access to the moon.

At the Hogwarts welcome feast, Dumbledore announced plans for a lunar Hogwarts Branch School and wizard settlements. Taylor was appointed acting Vice Principal to lead the expedition and construction team, leaving Andrew stunned at the prospect of being sent to the moon.
