I'm an unapologetic AD&D first edition Fiend Folio fan & user of all of the insane monsters within that incredible game book. The monsters in the Fiend Folio have served me very well & perhaps a bit too well. I've used all them from the first time I got the book & thumbed through it again & again for hours on end.
Among my absolute favorite Fiend Folio monsters is the Ettercap created from the life blood verse of Tolkein's Bilbo Baggins Hobbit. The Ettercap is a humanoid spider monster with the features of an insane man & the abilities of a spider. They are expert poisoners, web & trap builders, & very sneaky as well as stealthy in the extreme.
Wiki lists them as; "An ettercap is a race of bestial spider-men aberrations in the Dungeons & Dragons fantasy roleplaying game" But there's some very interesting fiddly bits & pieces about the Ettercap. First they are found in temperate locations such as forests, swamps, etc. & they are a nightmare in their home environment. Imagine making camp under the large noses of something like this.
They have an AC of six & there's a thirty percent chance of encountering them in their lairs which are going to be an obstacle course of webbed booby traps, dead falls, trip wires, & possibly even webbed poison walls. They attack like ninja using the natural terrain to their advantage & they keep loyal pet spiders. Even though their intelligence is low they are very cagey & cunning using pack tactics to take down larger groups of adventurers.
Adventurers don't actually stand a chance against these things because of the traps they lay & the fact that their senses are so keen. Ettercaps are going to strike at night & we can draw several conclusions from Russ Nicholson's Fiend Folio artwork.
But where did the Ettercap come from to begin with? There are several theories in mythology over the years strongly connected with much of the lore of Dungeons & Dragon's later editions. But I've got my own campaign origin for these monsters for they are the spawn of Arachne the spider goddess of Greek mythology even though her origin goes back much further. The most popular story of Arachne comes from the poet Ovid;
There is mythological evidence that the goddess had prophetic abilities & the abilities to divine the affairs of the gods. Her children inherited her bitterness toward the gods & their chosen heroes. She was consigned to the underworld. Rumors abound of Arachne being consulted by numerous dark gods, arch devils, demon lords, & many lower world powers some escaping her wrath barely. Many others gaining knowledge only to be consumed by her crazed lust & insane hunger for the supernatural blood of the gods.
Her children were consigned to the furthest reaches of the planes & outer dimensions . The Ettercaps were locked away from humanity for a time but they made war upon humanity. The bitterness of the Ettercap tribes knows no bounds even today. They still lurk on the outer fringes of the wildernesses & wastelands of many lands even to this day. Ettercap mercenaries & assassins were renowned in supernatural circles for their violence & ferocity in military operations of sabotage.

The Ettercap tribes have deep ties with the spiders of Leng in Earth's far future Dreamlands & with the spider creatures of Zothique. The Ettercap have a strong but murky tie with the spider goddess Atlach-Nacha as she is served by several tribes of the monsters. These worshipers are of slightly more dangerous variety of the Ettercap as they share the hatred of being disturbed from their devotion to their spider goddess. Her divine work of bridging the waking world & the Dreamlands is seen as all consuming. The Ettercaps of
Atlach-Nacha are some of the best trap makers & engineers in existence. They may be summoned by a monster summoning spell but must be paid with a live student of the arts & an offering of at least 780 gems worth of treasure before they will entertain a temporary assignment.
Don't cross the servants of Atlach-Nacha or they will not only eat the summoner but everyone else within a house or block. Only their webs left behind with odd & disturbing designs that no mortal should see.
These Ettrcap live for the day when the Earth will be cleared of humanity & they can once again take their rightful place under a blotted red sun.
