The bloated purple Spiders of Leng have long warred with that realm's more humanoid denizens, yet this does not make the Spiders allies of sane life.Artistic trap builders, Leng spiders construct lairs of dangerous and haunting beauty made of webs and other materials found nearby.A Leng spider's venom causes flesh to blister and rot away and the mind to experience vivid and horrific hallucinations—these visions cause the poisoned creature to react in an unpredictable manner, as if confused. The hallucination element of this poison is mind-affecting. Most leng spiders possess only 7 legs, but some possess 9, 11, or only 5—they never possess an even number. These are stats for the infamous titanic spiders, smaller versions do exist. " There were scenes of old wars, wherein Leng's almost-humans fought with the bloated purple spiders of the neighbouring vales; and there were scenes also of the coming of the black galleys from the moon, and of the submission of Leng's people to the polypous and amorphous blasphemies that hopped and floundered and wriggled out of them." -H.P.
