The crone rarely visited this particular building. She rarely needed the services it offered; that was one of the upsides of being a Fable. Of course, she knew that she could get hurt; she knew many things could happen to her. She knew that it was very possible given the right circumstances, she could die. But, the crone had a reason for being here at the Hospital. She had a vial of blood, two or more in fact to collect.
Baba wore her most becoming and most "innocent" sundress. The City being what it was, and she being who she was, she rarely worried about snow or cold, save for the time the City decided to play with snow. The sandals were bits of leather and board. She was nature's child; she even smelled like the elements - even if she was very clean.
It didn't take much coaxing to finally find the young doctor she wanted. He had something she had decided she'd need. So, upon finally reaching the lab, the crone smiled. Just a little bit of magic to give her desires a better chance, something to weaken the inhibitions, to heighten lust, and perhaps make the strange boy more malleable. With that in place, she knocked.
