d100 Horror Street Crime in Hell City

So after a recent binge of historic dramas and Napoleonic war stuff I went into my pulp and trash movie collection including modern attempts to recreate 70s exploitation cinema. Hobo with a shotgun is pretty awesome and I had forgotten how horrible the featured city is with poor Rutger witnessing awful crimes as he wanders the streets before his shotgun rampage. Judge Dredd and cyberpunk and often superheroes often feature horrible street crime. Your heroes are only as good as the villains they bust and the villains are only as good as the atrocities they perform.  I would use in my roadwar and cyberpunk settings. 

So anyway this table is for walking around god awful shit cities going to hell in modern era games but possibly useful elsewhere. Its to paint a picture of the god awful studs that happens around here. If your a reader who thinks my usual stuff is misery crawl and dehumanises my readers (as one reviewer said) well this post is like that dialled up a bit more. If your crime towns not always this bad you could use in a riot or just to grab news headlines.

It's as if civic authorities wanted the city to be this bad.

Sargassum Faction Generator

This is for settlements in the sargassum of which there are more than you expect except they have been brought here over centuries and all simultaneously inhabit similar space and are quite probably separated from their own kind. Some Aquatic races understand the faerie land nature of the place and build kingdoms here.

So you don't need to roll all of these things.
You could roll extra of the tables for bigger factions.

Most factions have a leader that might be smartest or strongest
-leader often has bodyguard
-leaders have mates and family around them

Most factions have a spiritual leader that might be their smartest
-most small groups have a senior initiate or acolyte at least
-often Priest, Wizard, Druid, Sorcerer, Monk, Shaman or whatever
-larger groups have multiple sects and places they gather

So faction has
-a lair
-type
-pets 1in6 have lots of domesticated
-strongest d3
-smartest d3
-resource

Then work out chief and possibly sub chiefs sets and spiritual leader
The strongest guys often end up if not chief end up as a champion or bodyguard
The smartest guys could be the main boss, spiritual leader or just an adviser or expert

Into the Sargassum part one

This is a vast sea choked with kelp like might forests beneath the sea and home to fabulous creatures. Strange weather, hauntings and sea phenomena keep visitors away before most get close enough to be eaten by monsters. As you enter you get drawn into another reality of stranded ships and monsters. Among the ancient wrecks humans survive and form savage societies. If youcame by boat someone wants it. Made of meat? Someone wants to eat you.

Ive done a bunch of sea themed stuff over years intending to do a comp. My Bloodsand Beach setting was so horrible ten years of players never visited and several times debated it when sighted then left. Lots of stuff on horrible encounters and my sea invade the land stuff all worth look and most are filed in a group in my sidebar links on my setting.

Part of the plan early on was to feature human seaside settlement, some stuff on ships and world maps and island generators. The dungeon part was a ruined city buried in a coral reef from an ancient civilisation with lots of fish folk hybrid sand worship of undersea demons. The top levels would have air, the lower ones dark and flooded and more horrible.

But the idea of Sargasso that meant Unclescrooge of Johnny Quest might visit and it literally had giant weed, hundreds of visible wrecks, mist and monsters. Of course dinosaurs, pirates, undead, cannibals and cults abound.

So like many of the settings I make, these are the core tables to do

Gigantic seaweed structures often rise above water level and as thick as mighty tree trunks. Often these growths lift old wrecks up even several stories above the water. Many you can walk on through the maze of the sargassum. The branches vary from a foot wide to two to six yards wide and sometimes bigger. People build structures in upper branches as homes.

The weed has many uses even as food and medicine. Many creatures live among it and on it like shellfish and crabs. Supernatural sea creatures from the marine faerie world thrive too, some petty spirits and divine beings living as local gods with thralls.

Tides and fog are common factors too. Certain levels or shipwrecks might be partly flooded with water levels changing with tides. Swimming skills will be very useful.
