Great Spider Civilization

The Great Spider Civilization was devised by Zak Arntson at Harlekin-Maus

Great Spiders are horse-sized intelligent creatures with sharp intellects alien to our own. They reside in vast murky forests and prey upon wildlife, hapless travelers, and each other. The most cunning join the Great Burrow beneath the surface world, a maze of tunnels and webbed chambers ruled by their Queen Mother.

Draw Great Spider tunnels and chambers in black. Great Spiders prefer to reuse rooms for lairs and larders, burrowing only when necessary or constructing new chambers from the Great Spider Burrowing table. If you don't have a cave complex, roll any die across your map and create one as described in the Primordial Age rules.

Pick a spot on the surface above the cave complex and draw a finger-wide forest. Now draw a tunnel connecting the forest to those tunnels. The caverns' primordial beasts are your first Great Spiders, and each cave is now a lair. Expand each cavern by a bead in size.

Each lair is two beads in size, and consists of a web and larder. Each Great Spider is represented by a. A is either captured prey (in a larder) or Great Spider Treasure. You may want to represent larder with white d6's to save space, setting the die's face to the number of. When tallying the current population, add up all Great Spider, including the Queen Mother. No lair may hold more than 5 except the Royal Larder, which may hold up to 10.

Make up a name for your Great Spider Civilization which reflects its arrogant, predatory nature.

The Age of Spiders ends if all spiders are wiped out, the only living spider is the Queen Mother, or the Web of Worlds is opened.

The Great Spider Year
At the end of each season, any unclaimed lair loses all. This includes the Royal Larder.

Spring
In spring, Egg sacs burst and prey multiplies. If the population is less than 8, subtract the current population from a d8 (with a minimum result of one). If the Great Burrow contains a Chamber of Countless Eyes, roll a 2d8 instead. This is the number of new Great Spiders who survived to adulthood. Fill empty rooms first, then draw any new lairs required, connected to the Great Burrow by a tunnel at least 1 thumb long. Place 1 and 1  in each newly-claimed lair.

Summer
In summer, Great Spiders hunt. For each Great Spider other than the Queen Mother roll a d6 on the Great Spider Hunting table. The Queen Mother does not hunt; her ravenous appetite removes d6 from the Royal Larder (it's okay to reduce her larder to zero).

Fall
In fall, Great Spiders burrow. First, the countless spiderlings expand their haunt. Enlarge an existing Spiderling Haunt or create a new one as described in Great Spider Burrowing, below.

Next, find the first entry equal to or less than the current population on the Great Spider Burrowing table that hasn't yet been burrowed. Draw the new chamber and connect it to an existing tunnel. Opening the Web is a special activity which can be performed multiple times and does not create new chambers. Great Spider Treasures are always crafted of weird materials (typically silk, chitin and bone) and serve equally weird purposes.

Winter
In winter, The Queen Mother collects her tribute while her sisters plot. Skip this season if the Queen Mother's Lair has not yet been burrowed.

If there is a Queen Mother, each spider removes 1 non-treasure from her larder (if available) and places it into the Royal Larder. Following tribute, the Great Spider with the most attacks the Queen Mother using the Voracious Appetites rules below. Every new Queen Mother should receive an appropriately sinister and spidery name. If there is a tie for most, two random contenders fight, hoping to challenge the Queen Mother next winter.

If there is no Queen Mother, the Great Spider with the largest larder moves herself and the in her larder into the Queen's Lair and Royal Larder.

In either case above, if there is ever a tie for largest larder, randomly pick two of these spiders to fight.

Voracious Appetites
Whenever a Great Spider attacks another, each spider rolls a d6 and adds the number of, including treasures, in her larder. The Queen Mother receives an additional +2. The loser is devoured and her removed. If the newly-unoccupied lair has a larger larder than the winner's, the winner may move into the lair. A new Queen Mother always moves into the Queen's Chamber, adding her own WB to the Royal Larder. In the case of a tie, both spiders are killed.

End of the Spider Age
For every Great Spider on the map, excepting the Queen, roll a d6. On a roll of 1-4, remove it. Those that remain are giant spiders as described in Wandering Monsters. If the Queen is still alive, the remains as a spider queen alpha predator, too cemented in her dominance of this world to leave for others. She uses the web rules as per giant spider Wandering Monsters.

All Great Spider Treasures remain. For every larder, roll a d6. If the roll is less than or equal to the, remove all but 1 , otherwise remove all. Also add 1 to the Spiderling Haunt area, Midden and Royal Larder. These are unnoticed loot from long-dead prey. Now proceed to the Great Disaster.
