In a giant hall full of pillars, a merfolk wearing armor respectfully addressed the high priest in black robes standing in front of the crystal ball. "High Priest, the migration of the people living at the borders has commenced. But the subterranean castle could only accommodate the people living in the capital. The subterranean castles of the normal little cities may not survive the upcoming Nether Whirlwinds. Should I proceed to report this?"
"Have you confirmed the number of Nether Sharks for this upcoming attack?" the high priest asked, looking at the crystal ball.
"According to the reports from the frontline, five giant Nether Whirlwinds have already been spotted. There are also about 100 big Nether Whirlwinds and about 800 medium Nether Whirlwinds. This is an unprecedented Nether Whirlwind frenzy." Desperation could be sensed in that merfolk's voice.
