That's not much of an answer, and Greta's brow furrows. Does Darrow's magic qualify as 'old'? She doesn't know much of the city's history -- the museum's local history exhibit was closed the last time she was there with Saoirse -- but obviously the place has existed for some time.

She follows Amalthea out the back door, her own cup of tea warming her fingers. "Besides the three of us? Sam's been by, and Biffy's seen it." But Sam has no magic she knows of, and Biffy wouldn't presume to meddle with her garden without a by-your-leave.

Then, belatedly, old magic and plant meddling collide with the memory of another visitor. "Galadriel," she says, and she could just about kick herself for not guessing right away. "It could be hers. She actually put me in mind of you, a little."
