"Yeah!" Delphi let out a cheer of excitement and fist-pumped the air at the important milestone. "We're in girls," she called down the ladder to them all. "It's game on!"
She climbed through the doorway. Ahead of her, there was a small vestibule with another locked door.
This one was more straightforward with a simple keypad lock that operated a mechanical opening mechanism. She plugged in the code Consort Cheales had given her, and the second door opened just as Feifei and Lili entered the vestibule behind her. She looked back at them both with a huge smile of delight.
The three girls hugged each other and jumped up and down with joy, turning in a circle like little children. As the rest of the girls climbed across the gap and tumbled inside, they all joined the laughing, jumping circle of Guerilla Girls.
When they had calmed down enough to continue on, Delphi poked her head around the corner. There was a complex-looking control room.
