|“||There were scenes of old wars, wherein Leng's almost-humans fought with the bloated purple spiders of the neighbouring vales.||„|
|~ H.P. Lovecraft , The Dream-Quest of Unknown Kadath|
There are hardly any descriptions of this species, but it appears that they are simply common spiders of disproportionate size. In fact, their young measure like an adult pony. They are also sometimes said to be purple in color.
When they find a place that satisfies them, they fill it with cobwebs and settle there permanently. They are very territorial and solitary: if another creature gets too close to their territory, even if it is of the same species, it is immediately attacked and devoured. Their cannibalistic attitude speculates on whether they attempt to devour their young once they are born; If this is true, it would explain the scarce natural growth in the number of members of the species.
The Leng Spiders were the first settlers of the oneiric Leng. They were considered daughters of Atlach-Nacha, but this did not intimidate Men of Leng, who started a war against them to expel them and prevent them from being a threat to their cities. After a long war, men of Leng prevailed and the spiders were on the brink of extinction.
- Due to her appearance and solitary attitude, She the Spider, belonging to Tolkien's literature, bears a great resemblance to spiders of Leng, in the same way that her mother, Ungoliant, has it with Atlach-Nacha.
