At Hogwarts, the Weasley twins’ dangerous electrical experiment injured Ron, but they later showed Vaughn and Hermione their Alchemical solution for Magic’s interference with electricity.

Dumbledore taught Vaughn how to roam the Aether, where Vaughn encountered an Aether ray, a mysterious bewitching light, and a Muggle’s dream world. After Vaughn used Persona Armor to steady his fragmented consciousness and explored how the Aether answered his thoughts, Dumbledore assigned him to learn how alchemists understood reality before pursuing his ambitions to unite Alchemy with Muggle knowledge.

• Dumbledore took Vaughn into the Aether and explained how meditation objects anchored wizards, how emotions guided roaming, and how strong thoughts could be consumed.
