Bianca Pohlo
After a lot of prevarication, Bianca reluctantly agrees to go with the group, telling herself that all this talk of monsters is just silly rumour blown all out of proportion. If anything, they might appreciate a rational mind to analyse the evidence without such foolish preconceptions.
She leaves (most of) her books with Ameiko, asking her to let her father know where she's gone if he should come looking for her - and almost abandons the idea of going along when she thinks of what he might say about it. But, the way Ameiko looks at her, almost as if she's impressed, toughens her resolve not to back out now. Besides, they'll be back in no time.
All in all, she's more than a little flustered as the group crosses the Turandarok, glancing around occasionally - and nervously - but mostly focused on her own thoughts.
