"Bye!" Ylva calls from the middle of the patterned floor. She twists the worldbridge and disappears in a swirl of stardust. "I will be leaving soon as well," Inric says. "I have discovered the location of another book. I need to go and collect it." "How long will you be away?" Colle asks as they head back to the study room. "I don't know. It shouldn't take long at all, but I expect there will be complications. Judging by past experience." His voice is dry and his face sober, but Colle recognises the humour and laughs anyway.
