Having Cleopatra waking up in a museum or a warehouse was what I had in mind. Instead of giving her a legion of servants though, I was thinking of having her work back from square one. The way I see it, she was all powerful back in her time, blessed with immortality and such, until she got careless, whether out of pride or cunning of the descendants, and she was sealed away. When she wakes up, she will seek to restore her power, and take revenge on those who sealed her away. Since that was thousands of years ago, she will have to settle on their bloodline. With them out of the picture, she can begin to turn the new world into her world.
We could start it like I initially thought of. The researchers get too eager with Cleopatra's remains, and the spell is disturbed. Late one night, the spell breaks and she rejuvenates. We can have one of the members investigate, preferably Michael. He would know ancient Egyptian and is not affiliated with those who sealed her. She seduces him, and he becomes her pawn to manipulate. Through her powers, she would gain knowledge of the new world. We could say she is drawn to the ones who sealed her, so finding them won't be hard. It seems too convenient to have them all work in the same place, but from what I read from the profiles, we could have them all come from different parts of the world, maybe a ploy to lure them close to her?
