What kind of magic is in the Labyrinth of Souls

When Unen Anchin contracted with the Vazra to construct the Labyrinth of Souls he stationed many adepts throughout the cave to monitor their work. 

The aether in the cave was thick and full on account of the Fox Warren within. So many spirits in one place calls the aether to it like metal to a magnate. 

Three Vazra entered the center of the chamber: one in red robes, another in blue, and the last in black. The color of the Vazra's robes may or may not have anything to with the arts they practice or if it is a mere whim, but none of the white clad specters entered the cave.

Their rite began with a red robed Vazra lighting a stone brazer in the shape of a dragon's head with flames gathered from the great wyrm Galyn Surgalt. As the red Vazra gathered the aether above the flame, a black robed Vazra chanted a Bibliothecary incantation for secrets to be revealed.

Twenty-four Vazra in total wove their enchantments into the stone of the cave. Noble metals of ever type were brought into the cave and wrought into the mechanism at the heart of the labyrinth.

Kitsune, tanuki, and all manner of spirit and yokai entered and left the cave in the six days it took them to build their magical wonder. Some believe they added their magic to the construction, while others think they simply looked about to see what the Vazra were doing.

In the end, only the Vazra know for sure, and they refuse to share their knowledge with any so none my devise a method to circumvent their discernment.

Other than the magic to read the hearts, minds, and spirits of the students, the labyrinth has produced the weapons and magical implements they would need to pursue their education. Something of the artificer's art must be built into the labyrinth for it to manufacture the equipment it leaves to those who find them.

Many who spent time in the labyrinth claim that it spoke to them in their dreams. While many of these stories are undoubtably apocryphal, the idea that the labyrinth is alive persists. Some have even claimed to see it wander the warren in the form of a ghostly blue lady.

In time, we many learn what secret arts produce such wonders. Until then, our pale speculations will have to suffice.
