Absurdist Web (Adventures in Zeitgeist)
Eighty-eight spider webs collected from within three miles of the corpse of a huge creature that died while entangled and poisoned.
This knot of fey spider silk unfolds into a ten-foot square, occasionally unearthing a long-dead sparrow or a cricket that waves thanks before hopping away.
This web functions similar to a portable hole , and can contain material that would fit in a 10-ft. cube. However, the user cannot see what is in the extradimensional space, and can only extract things they know are inside. Those attempting to divine the contents of the web via magic must succeed on a DC 28 Intelligence (Arcana) check. On a failure, the spell or effect is wasted, and the creature cannot attempt to divinatorily discover the contents of the web again until 24 hours have passed.
A creature placed into the extradimensional space is placed into stasis for up to a month, needing neither food nor water, but still healing at a natural pace. If a living creature is not freed within a month, the creature is shunted from the absurdist web and appears beneath a large spider web 1d6 miles away.
Food, drink, and unintelligent creatures placed in the web are consumed immediately by unseen entities, but dead sapient creatures are left alone and do not decay for up to one month. After that point, whatever etiquette fey spiders abide by treats them as fair game, and they are quickly devoured. Moving the web does not count as moving the body for the normal limit of three miles on resurrections and speaking with spirits.
Word has it that this web has a profound connection to the Webway, a series of space-folding tunnels crafted and frequently used by the arachnids of the Dreaming. The new fey titan known as the Hollow Widow would doubtlessly know more of these webs and the Webway.
