Nahida: (Reading the letter with a raised eyebrow) Oh, Tighnari always manages to surprise me. What now? (She picks up her phone and dials Tighnari's number, waiting impatiently for him to pick up.) Tighnari: (Excitedly) Nahida! You got my letter! I knew you'd be interested in the latest findings! Nahida: (Sighing) Tighnari, we have more pressing matters to attend to. I don't see how the size of Collei's busts is relevant. Tighnari: (Defensively) But Nahida, it's crucial! It might hold the key to understanding the cultural significance of fertility in Sumerian art! Nahida: (Chuckling) Tighnari, we can't base our entire research on that. We should focus on deciphering the ancient texts and rituals instead. That's what truly matters. Tighnari: (Reluctantly) Fine, I understand. But I couldn't help but be curious. Anyway, what's our next course of action? Nahida: We need to gather our team and head to the Great Library of Sumeru. There are ancient texts that might hold clues about the upcoming threat to our land. Tighnari: I'll make the necessary arrangements. How about I meet you at the library in an hour? Nahida: Perfect. And Tighnari, try to keep your attention on the task at hand and not... other distracting subjects. Tighnari: (Sheepishly) Right, I'll do my best, Nahida. (They hang up, each preparing for the challenges that lie ahead in unraveling the mysteries of Sumeru.)
