Ren lowered his gaze for a moment, then nodded. "I understand. But where does this crack?"
Veylan shook his head lightly. "These cracks are found in one forbidden area. It will help you to find where a grand calamity will happen."
Ren frowned. " So according to that we have to find these convergence points."
Veylan leaned back, his eyes distant as if weighing years of research. "Yes, you are right. You have to find this after gaining all five keys. It will help us to find where the main grand calamity will happen. Yaah, we know where it will happen but sometimes its positions suddenly change. So for exact information we have to measure this."
Ren's brow furrowed. "So the old records were wrong?"
