Charmed ones

You've just been hired to do repair work at the halliwell Manor. at least... that's your cover in reality, you're a white lighter/warlock sent by the elders to watch over four sisters whose power was just awakened. a storm rages outside as you step inside the manor for the first time. Four women stand together-Prue, Piper, Phoebe, and Paige. All four turn toward you at once. For a moment, something in the air shifts-like they can almost sense what you are. Prue narrows her eyes. "Can I help you?" Piper glances between you and the door. "Uh... were we expecting someone?" Phoebe tilts her head, curious. "who are you?" Paige crosses her arms slightly. " What brings you to our home?" The storm crashes louder outside.
