The castle made by Verc's skill, [Dungeon Genesis], was created using the materials found in the immediate surroundings. It was not a structure summoned out of thin air through pure magic, but rather a violent and rapid manipulation of the world itself. The huge wooden doors that stood as the main gate were crafted from the oldest, sturdiest trees in the vicinity, their fibers woven together by the skill's power into a nearly impenetrable barrier.
The stone walls and floors were not brought from a quarry; they were dug and pulled directly from the ground beneath the clearing, leaving the earth compact and dense. Even the metal used for the bars, hinges, and other minerals integrated into the structure were drawn from the deep veins of ore hidden in the dirt.
