The Dwarven Clan! Princess or Crossdresser?

It was in the late hours of that night.

"Rumble rumble rumble~~~ rumble rumble rumble~~~"

A strange noise echoed from beneath the depths of the Giant's Valley, causing the ground to tremble slightly.

Eric was quickly awakened by the commotion.

"What's going on?!" Being awakened in the middle of the night would irk anyone, and Eric was furious at this point.

"Master, this humble servant forgot to inform you... Recently, our Giant's Valley has been frequently experiencing these strange noises in the middle of the night," Modesty hurriedly explained to Eric.

"Have you found out the reason for this?" Eric inquired.

"It's the Dwarven Clan! Their underground kingdom is located thousands of kilometers away in the Hawkstone Canyon, but recently, they discovered a vein of mithril near our area, so they dispatched a large number of female dwarf miners to excavate it."
