Westover Hall
The book opens with Thalia Grace, Annabeth Chase, and Percy Jackson in Sally Jackson's car as she drives them over to Westover Hall in Maine, where satyr/Protector Grover Underwood has found two powerful demigods (later revealed to be Nico & Bianca di Angelo). They stumble across a teacher (Ms. Gottschalk) and the school's vice-principal, Dr. Thorn. The two have not seen the kids before, and appropriately want to throw them out. Thalia manipulates the Mist to convince Ms. Gottschalk into believing that the three were students that had been attending the school for some while now. It is made obvious that Dr. Thorn isn't buying it, but he backs off.

After meeting up with Grover, the satyr informs the trio that Dr. Thorn was a manticore and was suspicious about the Angelo siblings. Thalia makes a plan, suggesting that all of them try to "mingle." Thalia goes off with Grover and Percy is left with Annabeth. Of course, the plan doesn't work out. Annabeth shifts into the crowd, leaving Percy alone. Percy sees Dr. Thorn trying to sneak away with the Angelos, so Percy follows.
