"The unnatural chambers and corridors of the Silver Tower are lair to myriad monstrous beings. Around any jagged corner or winding crystal stair, the Gaunt Summoner's captives might encounter terrifying enemies the likes of which they have never seen. Tzeentch delights in endless variety, and so the denizens of the Silver Tower are as uncountable and diverse as the scintillating grains of sand upon all the shores of the Mortal Realms. So vast is their number that the Gaunt Summoner has forgotten many altogether, leaving them to wander the tower at will. Any attempt to comprehend the profusion of strange creatures said to infest the Silver Tower would drive a mortal mind to madness." (Warhammer Quest: Silver Tower Guidebook, p.32)

"Not all the denizens of the tower are there by the Summoner's will. Green-skinned invaders proliferate in the dark, sprouting like fungus and spinning their webs to ensnare the unwary that they might be devoured. Magical beings there are too, capricious manifestations of the tower itself. These freakish creatures serve no master but the Silver Tower, and help or hinder as the whim takes them." (WQ: ST Guidebook, p.33)

"Grot Scuttlings infest the Silver Tower's dark depths. They are wily and tribal, half-arachnid beings whose poisons and webs are the bane of the unwary. Though individually weak and cowardly, when massed in great swarms the Scuttlings can overwhelm even the greatest of warriors, before dragging their venom-bloated corpses away to dangle in their carrion webs." (Age of Sigmar Grot Scuttlings Warscroll)

"Those little critters were really fun to make. Goblins are a classic dungeon minion, as are spiders, so we decided to combine them together. The story goes that these grots started eating a weird fungus that grew on giant spiders, which, over time, caused them to mutate. It just goes to show that you are what you eat!" (Architects of Fate, WQ: Silver Tower design interview)
