Ch. 405Why the Collision Happened
Peeves explained that the Basilisk, named Basilis, was an intelligent guardian of Hogwarts who had been kept beneath the school and periodically put into hibernation. He revealed that the Basilisk had awakened early and lunged at Jon, leaving the cause of the collision explained but the reason for the sudden awakening unknown.
- Jon asked Peeves why Slytherin's Basilisk had been kept beneath Hogwarts, and Peeves warned him not to call Basilis by the creature's kind.
- Peeves described how Hogwarts became the last stronghold of the wizarding faction after the Papacy's war devastated the wizarding alliance, prompting the Founders to reinforce the school's defenses and build its prisons.
- Peeves explained that Basilis guarded the Slytherin family's property and was kept alive through feeding and a Magic array that replayed Parseltongue to induce hibernation.
- Peeves said that fifty years earlier, the young Dark Lord had opened the Chamber of Secrets and used Parseltongue to control Basilis, causing years of trouble at Hogwarts.
- Peeves explained that Basilis had woken early again, and Hogwarts' recovering consciousness suppressed him as he lunged at Jon.
