Muffled drums beat out a nerve-scratching rhythm, and red lights flickered hypnotically in the underground Temple of Hates, where five thousand ragged worshipers knelt and abased themselves and ecstatically pressed foreheads against the cold and gritty cobbles as the trance took hold and the human venom rose in them.

The drumbeat was low. And save for snarls and mewlings, the inner pulsing was inaudible. Yet together they made a hellish vibration which threatened to shake the city and land of Lankhmar and the whole world of Nehwon.

Lankhmar had been at peace for many moons, and so the hates were greater. Tonight, furthermore, at a spot halfway across the city, Lankhmar's black-togaed nobility celebrated with merriment and feasting and twinkling dance the betrothal of their Overlord's daughter to the Prince of Ilthmar, and so the hates were redoubled.

The single-halled subterranean temple was so long and wide and at the same time so irregularly planted with thick pillars that at no point could a person see more than a third of the way across it. Yet it had a ceiling so low that at any point a man standing tall could have brushed it with his fingertips — except that here all groveled. The air was swooningly fetid. The dark bent backs of the hate-ensorceled worshipers made a kind of hummocky dark ground, from which the nitre-crusted stone pillars rose like gray tree trunks.

The masked Archpriest of the Hates lifted a skinny finger. Parchment-thin iron cymbals began to clash in unison with the drums and the furnace-red flickerings, wringing to an unendurable pitch the malices and envies of the blackly enraptured communicants.

Then in the gloom of that great slitlike hall, dim pale tendrils began to rise from the dark hummocky ground of the bent backs, as though a white, swift-growing ghost-grass had been seeded there. The tendrils, which in another world might have been described as ectoplasmic, quickly multiplied, thickened, lengthened, and then coalesced into questing white serpentine shapes, so that it seemed as if tongues of thick river-fog had come licking down into this subcellar from the broad-flowing river Hlal.
