Gix - Teaches followers how to summon him

Their chant was logical and precise, their motions practiced and machinelike. They had been taught how to call upon Gix before they left Koilos, and the demon had left precise instructions when to call upon him. Now, in the windowless room of their small quarters, the twenty-four brothers chanted the proper dirges and motioned their hands in the proper manner, carving symbols in the air.

In return, the air winked at them, coalescing into a great pillar of blackish smoke, smelling of burning oil.

There was the sound of crashing gears, and from the smoke stepped their master, Gix, resplendent in his living armor, his snakelike tendrils flexing and coiling from the back of his head.

"You have summoned me," said Gix. "I trust it is for a good reason."
