The Demon Flower of Lophai demanded sacrifices, for it was not a peaceful and passive flower such as those found on earth.
excerpt
Not as the plants and flowers of Earth, growing peacefully beneath a simple sun, were the blossoms of the planet Lophai. Coiling and uncoiling in double dawns; tossing tumultuously under vast suns of jade green and balas-ruby orange; swaying and weltering in rich twilights, in aurora-curtained nights, they resembled fields of rooted serpents that dance eternally to an other-worldly music.
Many were small and furtive, and crept viper-wise on the ground. Others were tall as pythons, rearing superbly in hieratic postures to the jeweled light. Some grew with single or dual stems that burgeoned forth into hydra heads, and some were frilled and festooned with leaves that suggested the wings of flying lizards, the pennants of faery lances, the phylacteries of a strange sacerdotalism. Some appeared to bear the scarlet wattles of dragons; others were tongued as if with black flames or the colored vapors that issue with weird writhings from out barbaric censers; and others still were armed with fleshy nets or tendrils, or with huge blossoms like bucklers perforated in battle. And all were equipped with venomous darts and fangs, all were alive, restless, and sentient.
They were the lords of Lophai, and all other life existed by their sufferance. The people of the world had been their inferiors from unrecorded cycles; and even in the most primitive myths there was no suggestion that any other order of things had ever prevailed. And the plants themselves, together with the fauna and mankind of Lophai, gave immemorial obeisance to that supreme and terrible flower known as the Voorqual, in which a tutelary demon, more ancient than the twin suns, was believed to have made its immortal avatar.
The Voorqual was served by a human priesthood, chosen from amid the royalty and aristocracy of Lophai. In the heart of the chief city, Lospar, in an equatorial realm, it had grown from antiquity on the summit of a high pyramid of sable terraces that loomed over the town like the hanging gardens of some greater Babylon, crowded with the lesser but deadly floral forms. At the center of the broad apex, the Voorqual stood alone in a basin level with the surrounding platform of black mineral. The basin was filled with a compost in which the dust of royal mummies formed an essential ingredient.
The demon flower sprang from a bulb so encrusted with the growth of ages that it resembled a stone urn. Above this there rose the gnarled and mighty stalk that had displayed in earlier times the bifurcation of a mandrake, but whose halves had now grown together into a scaly, furrowed thing like the tail of some mythic sea-monster. The stalk was variegated with hues of greening bronze, of antique copper, with the livid blues and purples of fleshly corruption. It ended in a crown of stiff, blackish leaves, banded and spotted with poisonous, metallic white, and edged with sharp serrations as of savage weapons. From below the crown issued a long, sinuous arm, scaled like the main stem, and serpentining downward and outward to terminate in the huge upright bowl of a bizarre blossom — as if the arm, in sardonic fashion, should hold out a hellish beggar's cup.
