During the two weeks that Briallen and the others in her potions class were sequestered in the infirmary, Luna took it upon herself to investigate the odd sensations she’d sensed floating around Adalricus Dumbledore’s aura. As quietly and stealthily as she could, she trailed after the Slytherin Dumbledore wherever he went. She noticed that at times, he was like any other student learning spells, taking notes, and spending some time in the library. But occasionally, his aura read as if he were a clone of Albus Dumbledore. It confused her greatly and strengthened her resolve to solve this strange mystery. She tapped into a rarely used ability of hers to disguise herself using the masking powers of her aura to blend in with the surrounding environment.
