1. Revelio/Reveal
"Welcome to the Leaky Cauldron," said the ginger in a dull voice. "I'll be your waitress this afternoon. Do you need another minute to decide?"
"No, thank you," the raven-haired beauty said lightly. "I'm ready."
"Can I start you off with something to drink, then?"
"Erm, I'd like one order of . . . the Phoenix Firewhiskey?"
The ginger's head snapped up. "You want an order of the Phoenix?" she repeated, just to be sure. The beauty nodded. "Of course. Only, I'm awful busy - " (the pub was almost completely empty) " - and it'd really help me out if you could come back to the kitchen and get it for yourself."
"Um. . . ." The beauty looked nervous. "Okay."
"Good. Follow me, then."
The ginger led the beauty back behind the bar and into the kitchen. "Revelio," she muttered to a cabinet next to the oven. A door sprung forth and opened to reveal a set of stone steps leading down into darkness. "You're new, huh?" the ginger asked as the beauty gawked at the chasm. "I'm Ginny. You're one of the first ones here, they usually don't come in until after nine."
"Oh." The beauty's face turned red. "I didn't know."
"Don't worry about it." Ginny offered a tight smile. "Just go down the steps and wait for the rest of the members." The beauty looked terrified. "It's not actually that dark. It's a spell we use to make it less conspicuous."
"Will I be the only one down there?"
"Nah, George Weasley - my brother - and Katie Bell are here. They're always here. They like to stay away from all the action. Plan strategies from afar and all that."
"Oh." The beauty looked relieved. "I know Katie's sister. She recruited me."
"Good. Then you'll have friends." Ginny craned her neck to see around the corner. More people were lining up at the bar. "I've got customers, but you go ahead down. Make yourself at home."
"Thanks, Ginny." The beauty smiled gratefully.
"No problem." Ginny scooped up a tray of dirty dishes and balanced it against her hip. "Welcome to the Order of the Phoenix."
