In the days following the sudden introduction of Sandrine to the school population, both serpent and Briallen became instant celebrities, more so for the human half.  Those injured or petrified were returned to their previous healthy states by the Healers who’d been brought in while the Unspeakables descended upon the school, both to return Sandrine to her nest and to check over the Chamber once again now that the Guardian understood what it was they were doing there. While down there, Sandrine pointed out the location of Salazar’s office and a couple of other hidden rooms she knew about while observing her Master as he worked during the creation of the Chamber. She informed them via Speaker that there had been one other that had breached the defenses last year and had been neutralized. Croaker realized soon enough that she’d meant the disappearance of Auror John Dawlish during the assault on the castle during Albus’ failed attempt to wrest back control of Briallen Potter and made a note of it to inform Amelia so his name could be taken off the rolls of those missing in action.
