"Good morning," Colin greeted her as he stood in the corridor.
"Good morning," Shelley nodded briskly and added, "Let's go."
As she looked at Colin, she thought for a moment and then said, "You had better disguise yourself."
Colin nodded slightly, and with a thought, the bones and skin of his face subtly shifted, instantly transforming him into an unremarkable, ordinary young man.
Shelley looked at him closely and suddenly asked, "What kind of witchcraft is this?"
Seeing the inquiry in her eyes, Colin explained simply.
Sometimes, in the Wizard World, such true physical changes are harder to detect and more useful than disguises made by witchcraft.
Shelley led him out through a small door, about one person tall, at the back of True Knowledge Society Castle.
The door opened onto a secluded alley, at this point they were both fully disguised.
About half an hour later, the two walked side by side to a common shopping street.
