Lunasa

Hello, I've played up to chap 17 and I have enjoyed this hack a lot. According to the order of recruitment list that was posted though, I'm having trouble recruiting a certain Tanya (never even saw her), and the pair of Cynthia and Eliana. Algimas couldn't talk to them, would Wayland be able to? I have read the dialogues before each chapter and the augury but haven't quite figured it out... If anyone could tell me, I would be grateful.
