The Triax was the ultimate evil union of three magicians, that when joined together caused the Eternal Night to fall upon all of Quendor. This prophecy had been spoken of by the Zizbits since before even the downfall of Pheebor in 396 GUE:

Six eyes and six hands for the Triax,
Inscribing the arc spell in the sand.
The runes foretell the fate of Quendor:
A reign of darkness upon the land.
Two eyes, two hands have mother’s form,
Two hands and eyes were backwards born.
The last pair for one skilled in sorcery,
Who, imprisoned by mage, by that mage is set free.
When these three twos join at Phee and Bor,
The Triax will rule from shore to shore.

In crystal ball, magician trapped
Avoids for now intended death.
His vile soul at random spills,
And taints the air with dire breath.
Seven spills of power, then all is sapped.
Seven bursts count the fatal trend.
For if not yet freed from his prison –
The mage then meets his end.

This prophecy was fulfilled in the mid-tenth century (c. 957-966 GUE) when the witch Moog stole a Zizbit spellbook. She was the one spoken of in the passage, "Two eyes, two hands have mother’s form." Her childhood friend Slye, by being born feet first, was the second, "Two hands and eyes were backwards born." And Radnor, one of the most skilled of all sorcerers, had recently been imprisoned in a crystal by Frobwit the Fair. "The last pair for one skilled in sorcery, Who, imprisoned by mage, by that mage is set free." Moog sought to bring the trapped magician to her before his "seven spills of power" were "sapped."

Moog inscribed the three runes of the arc spell upon the sands where the Bor and Phee Rivers met, and Slye and Radnor were summoned to her point when the time was right. Combining their powers together, ominous thunderclaps proclaimed the onset of this new reign of darkness as a black pall settled over all the land. The rivers and the seas turned to blood, as the charred land gave up its nurturing spirit. Although the records of this period are wanting, this grim tyranny would take many seasons and much valor to undo. But eventually after much hardship, tranquility returned to Quendor.
