Kicking off new Black City posts with a Bestiary collection. It's projected to be an 8 level dungeon so there's a need for a lot of monsters. Taking a cue from the Dismal Depths (and Evan's place) here's a look at the Bestiary so far. I've got a list below of future creatures (most of those are strictly dungeon level 4 and deeper beneath the City). Stats are somewhat "LOTFP style" since that's the core rules I'd use. I still need to edit these entries and adjust the balance between brevity and detail.
Ape Men of the Black City:
AC as Leather, MV 12, HD 1, Atk - Club 1-6, ML 9, AL C. Matriarchal white haired proto-humans that wield clubs and throw rocks. Gangs of male apes patrol areas in the city; females display a creepy attraction to human males.
Berserker Stage 1
AC as Leather, MV 12, HD 1+1, Atk - By Weapon, ML Special, AL C. Humans infected with the rage worm parasite from polluted water. Enter a blind rage during combat and never check morale, +2 on to hit rolls due to ferocity.
Berserker Stage 2
AC as Chain, MV 9, HD 3+1, Atk - By Weapon +1, ML 9, AL C. Prolonged rage worm infection mutates the victim into a larger, musclebound, feral human, with oversized jaws and teeth, that craves human flesh. Very stealthy, they surprise on a 1-3.
Berserker Stage 3
AC as Chain, MV 9, HD 4+1, Atk - By Weapon +2 or 1d10, ML 10, AL C. The final stage of rage worm infection causes the misshapen victim to grow larger than man-sized (8-10' tall). Often build cave-like lairs to larder food and suck bone marrow.
AC as Leather, MV 12, HD 1+2, Atk 1hp, ML 7, AL N. Swarms of 3' long worms with hag-fish mouths that infest the Warrens; attach on a successful bite and drain 1hp per round blood for 2-4 rounds before dropping off. Hinder movement.
AC as Unarmored, MV 1, HD 2 per 10x10 area, Atk Paralysis, ML 12, AL N. Fungal growth in the Warrens of Decay. The matrix generates a powerful toxin; terrestrial creatures that touch it must save versus paralysis or be helpless for 1-6 turns. Croach-Matrix encases paralyzed creatures in 1-10 rounds and slowly dissolves the creature while it's still alive, feeding nutrients into the Warrens. Croach-Matrix burns.
AC as Leather, MV 15/30, HD 6, Atk 3d6, ML 9, AL C. Evil winds from the arctic, offspring of the walker in the wastes. Deals 3d6 damage from scouring icy wind. Limited vulnerabilities.
AC as Chain, MV 12, HD 1+1, Atk By weapon or spell, ML 8, AL C. Servants of the Queen of Air and Darkness, these evil elves explore the ruins on her behalf. Typically carry sleep and charm spells, icy rapiers and cold ray wands that do 1-6 damage per level of the Dokkalvar. Immune to sleep, charm, and cold attacks.
AC as Leather, MV 6, HD 8, Atk 2-16, ML 12, AL C. Gjenganer that cannibalize other Gjenganer (see below) can become Draugur, ghouls capable of growing to twice their size and capable of delivering massive slams. When first encountered, they will appear man-sized and grow during combat. Draugur devour the slain. Have standard undead immunities.
AC as Chain, MV 6, HD 1, Atk - By weapon or spell, ML 8, AL C. Deformed race of evil dwarves from Nidavellir that seek gems and magic. Many of them can cast spells. Can become invisible at will.
AC as Leather, MV 6, HD 1-1, Atk - By weapon, ML 7, AL C. Vicious goblinoids spawned from rodents dunked into the ichor of the severed Joten head. Cruelty to other creatures is matched only by their desire to capture and dunk more rats. Resist cold, hampered by daylight (-1 on to-hit rolls).
AC as Leather, MV 9, HD 2, Atk - bite, 1-4 + poison, ML 7, AL N. Adapted for life in the city; always attack first. Hunted by frost goblins (since snakes hunt rats). Save vs poison or die.
Giant Furry Snake
AC as Chain, MV 12, HD 4, Atk - 2 bites, 1-4/1-4 + Poison, ML 8, AL N. These 10' long furred sea snakes hunt aquatic mammals on the islands; sometimes enter the ruins. Save vs Poison or die.
Gjenganer (Hungry Dead)
AC as Leather, MV 12, HD 2, Atk - 2 claws and bite, 1-3/1-3/1-3, ML 9, AL C. Humans and demi-humans that die within the dungeons must Save vs Death or rise in 1-6 turns as Gjenganer, hungry dead fueled by the energies of the Dark Goddess trapped in the depths of the dungeon. Intelligent; some newly risen Gjenganer don't realize they're dead. Driven to cannibalism by the urges of the Dark Goddess. Have standard undead immunities. See also Draugur, Hungry Bones, Moaning Shambler.
AC as Chain & Shield, MV 12, HD 2, Atk - bladed forelegs, 1-4/1-4, ML 11, AL N. Scuttling automatons that serve the Overmind and maintain the Warrens of Decay. Insert corpses into the Croach-Matrix to fuel the Warrens. Front legs have retractable blades.
AC as Plate, MV 9, HD 4, Atk 2 claws, 1 bite, 1-6/1-6/2-12 ML 12, AL N. Victims abducted by the Winged Terrors are taken to the Tower of Pain to have their heads removed; the bodies are fitted with fungal symbiote units. Surgical alterations include gigantic stomach mouths, armor plated implants, various claws, hooks, and bladed implements attached to their arms.
AC as Leather, MV 6, HD 1, Atk - 2 claws and bite, 1-2/1-2/1-3, ML 12, AL C. Moaning Shamblers that persist long enough lose their flesh and sinews, but not the hunger; they become ghoulish skeletons. Unintelligent. Have standard undead immunities. Take minimal damage from non-blunt weapons.
AC as Unarmored, MV 9, HD 1, Atk By Weapon, ML 10, AL N. Tall, slender creatures with jackal heads. Most are spell casters and can cast magic user spells; levels higher than 1 are possible.
AC as 7, MV 9/18, HD 1/2, Atk 1-3, ML 6, AL C. Flying cousins of the frost gremlins, they use small sized makeshift weapons. Five or more mites close together create a chaotic aura that reflects spells, critical misses, and fouls mechanical gear.
AC as Unarmored, MV 6, HD 2, Atk - 2 claws and bite, 1-3/1-3/1-3, ML 12, AL C. Gjenganer that can't maintain a flesh diet undergo rigor mortis, lose their inhuman intelligence, and begin to stiffly shuffle like traditional zombies. Have standard undead immunities.

AC as Unarmored, MV 12, HD 2, Atk By Weapon, ML 7, AL N. Primitive cave men living in the Warrens, they survive by following the leadership of She Who Must Be Obeyed.
Plastical Mark I
AC as Leather, MV 12, HD 3, Atk By Weapon, ML 12, AL N. Plastical, from Plastic-Alien, are rubbery humanoids with bulbous heads and large black eyes. They're fabricated by the city's machinery as workers. The Mark I often carries a heavy wrench (treat as club) and can be seen repairing doors and dungeon fixtures. (Obviously, I love me some Castle Amber with these Plasticals).
Plastical Mark II
AC as Chain, MV 12, HD 4, Atk Squeeze, 1d10 acid, ML 12, AL N. The Mark II was designed for hard to reach ducts and tunnels; it can stretch 20', envelope a target, and secrete an acid; roll open doors to break it's grip.
Plastical Mark III
AC as Plate, MV 12, HD 5, Atk By Weapon or Lightning, ML 12, AL N. Mark III's were designed to work on electrical equipment and glow faintly; thrice per day they can fire a 3d6 lightning bolt.

AC as Leather, MV 12/15, HD 3, Atk Special, ML 7, AL C. Alien creatures, half moth, half crustacean, half fungus. Abduct humanoids for unearthly experiments. Attack with otherworldly weaponry - paralysis rays, lightning guns, stun nets - unuseable by humans. Can drone once per day to create 30' sleep effect.
These are things in the standard bestiaries that still need to be added:
Northman Viking variants (Bandits, Nobles - Hersir with Huskarlar, NPC Party, Traders, Veterans). "Dire" animals infected with rage worm. The Warrens are full of giant insects of all stripes, vicious rodents, and fungi monsters. Traditional necromantic undead are not unknown - wights, wraiths, et al. Some automatons and golems (besides plasticals) need to be created.
Insectoid Hive Creatures
Machine Mind (Boss Overmind)
Reconstituted Alien Terror (the Resurrected)
Servitors of the Pool
Thing in the Pool
Vegetal Controller and Pod People
