Monsters and Beasts
Well, they told him not to take the brown acid, and here's where the bad trip starts. The gods have a certain amount of horror appeal – mostly because they're vast power attached to poor impulse control. The Monsters, on the other hand are almost entirely horror appeal. And one of the chief sources of that is their origin: all monsters are former humans, and that brings with it all the usual baggage for that trope, like the sympathy for someone forced to live a monstrous existence, and the anxiety that the same thing could happen to anyone, even you or your loved ones. They all have a 'psychological damage' section, noting the kind of symptoms that exposure to them will bring on in people they traumatize.
Most monster conversions are brought about by contact with the gods, although there are other ways – unrepentant murderers can spontaneously become Heightless, self-centered complainers can wake up as Skinless, and so on; naturally all the monster-generating behaviors are forbidden by Mad Lander society. All monsters are defined by their lack of something, defining them as less than human even though they may have great powers. All have a list of examples of how they could be generated: someone stamped flat by one of the Kikavos may become a Boneless, someone dismembered by a swipe of Gakox Pezep's paw may become a Soundless, and so on. A lot of monsters potentially have Shamanic powers (more on those later) which allows them to be a more customizable threat.
Bloodless
A lot like
Daybreakers vampires: if they consume enough human blood, they're basically ageless humans. If they start to go hungry, they go emaciated and get a big boost to their physical stats (and some nice damage immunities). If they continue to go hungry, they're in agony and start to permanently lose their minds. Bloodless never really die; even chopped into chunks, their consciousness remains intact and starving forever after.
Boneless
A flying skin-blanket with eyes, something like a really disturbing airborne manta ray. They have animal intelligence and kill by smothering with their embrace while exuding digestive juices through their underside.
Faceless
Normal-looking except for their
Question-like visage, the faceless are stalkers and jinxes. They imprint on people who come too close and follow them relentlessly, trying to cling to them in a pathetic embrace. All the while, dreadful bad luck affects anyone near the thing, the closer to the Faceless, the worse the luck. Fighting them is difficult because of the misfortune aura, and even dismembered they will continue to follow their target, severed fingers crawling like inchworms, eyeballs rolling through the dirt, intestines slithering like snakes.
Fleshless
No skin, no muscle; skeletons with organs. Very physically powerful, they are mentally torn between a violent hate for all human life and a consuming desire to be accepted in human society. The basic story is that one of these horrible things shows up, doing its best to
pretend it's ordinary folks, and as soon as anyone shows signs of not buying their (astoundingly unconvincing) ruse, it's murder time. If there are multiple Fleshless, they'll pretend to be a family, or even a community.
Footless
An eight-foot long foot with proportional shin, with a mouth and a single giant eye on the shin. Completely insane, they mutter all time and seem to have access to all knowledge, in unorganized form, so if you can sneak up near them you can try to sift through their babble for actually useful info.
Headless
Lacking heads, they have faces on their torsos Arnim Zola-style. Animalistic brutes, with ridiculous strength, they basically just hulk-smash any non-Headless they come across - they'll even go after gods.
Heightless
One-to-three foot tall serial-killer puzzle monsters. These guys get a big mental boost from their monsterism, but no physical augment. As long as they ritually murder at least two people per year, they can only be killed by one thing. That one thing varies between Heightless and can be basically anything: fire, drowning, a beetle walking over its left boot, etc. They like to get their kills in the style of Batman villains, giving warnings and setting up elaborate deathtraps, all to emphasize their superior intellects and their victims' helplessness.
Skinless
All gross bare muscles and monstrous strength, Skinless develop strange manias, and also live in a constant low level of pain which is only eased by killing people. Groups of them can skin humans for two purposes – either to convert them into more skinless, or to wear the skin for identity theft, but those are more-or-less mutually exclusive.
Soundless
A dismembered person, if each separate part sprouted tiny legs and venomous needle-toothed mouths. They also make no sound at all (automatically succeeding on all sound-based Stealth checks) which has obvious horror applications. Their venom is paralytic, so their victims can wake up unable to move as the silent pack begins to feed...
Weightless
Basically an exotic kind of living ghost, they've lost the ability to interact with the physical world except by being perceived. They pursue a variety of goals, from ghost-type unfinished business to tricking people into treating them as humans so they can forget their state for a little while.
Beasts
Stats for the local wildlife, most of which are North American to go with the Amerindian aesthetic. Most are basically normal, except for the seals, which are sapient, capable of speech, and seen by the Mad Landers as closer to human than foreigners. Some can perform a kind of sorcery, but they know the Mad Lander fear/hate of magic and keep it secret from them. There are also a couple of sample mutant animals, which occur when normal animals encounter divine energy: the Desire Snake is a snake which causes nearby humans to hear their own voice listing their most secret desires over and over; and the Raccoonalisk is a raccoon with flesh-melting eyebeams.
