Unfortunately, fighting spiders is a loud activity, which attracts spiders. Either they are sneaky or their approach was quieter than the thrashing of the dying one on Jann's sword. Either way, Jann now has two more spiders to deal with, and one has found Emmalina.

When the spider brushes her arm, she shrieks and wrestles her dagger free. It's dark, too dark, she can't see anything, but she can feel it moving and maybe she can't kill it but she will stab anything that gets close to her.
