Tarma walked into the library, really wanting to get some reference material for an odd thing she'd been noticing. She didn't get spooked very easily, but lately, just sometimes, she'd see a person who had what looked like two shadows. She'd looked for the sources of light which might be causing the two shadows, but never saw anything which could account for it.
So, she thought - "I'll go to the library. If nothing else, Madam Pince will know where to find information on that!". However, walking in, she noticed ... the person in front of her had two shadows.
Carefully, she walked around that person, toward the center of the room, and looked for Madam Pince.
