So, werewolves only transform once, after they were infected, either by another werewolf or by an unknown disease. From there, they remain in a human/wolf hybrid form with their human mind intact (except for the necessary firmware updates). The "animal side" only takes over either during full moon or when the werewolf is really scared.
In terms of psychology, the animal side behaves like a wolf that considers humans prey. That's all. A werewolf, controlled by their animal side, won't necessarily be aggressive; injured and scared werewolves will run, especially when alone.
Obviously, since they aren't inherently evil and because they still care about humans, werewolf tribes lock themselves up during full moon.
Now, temporarily trapping the tribe has several difficulties:
Purebreds: Purebreds are born as werewolves and make up the majority of most tribes, other than that, they aren't different from the ones who were once humans. I never said werewolves were sterile, which means tribes can get pretty large.
Werewolves are good climbers: Being stronger and more agile than regular humans, though not to ridiculous degrees, makes them difficult to contain AND keep safe. These are werewolves, not catgirls, if they fall, it's gonna hurt. Similarly, if they try to overcome other physical barriers through sheer force, they could end up hurting themselves.
They have to get out of there once full moon is over, and only when full moon is over.
They have limited resources: Werewolf tribes avoid humans and in terms of material and intellectual resources, they're also limited. Most werewolves were humans (usually from cities) with various jobs before they were turned. They, of course, pass the knowledge down to their children, but that's all.
4.5. Resources: In terms of resources, the problem is the limited "territory" and nomadic lifestyle. Werewolf tribes usually stay in heavily forested areas, as they're adapted to those and because it makes it difficult for monster hunters to track or pursue them.
Using the help of humans is obviously out of question. So, just how could werewolves hole up somewhere and wait out full moon while minimalizing the risk of injury/death of nearby humans or their kin?
The world's technology is the same as late-medieval Europe.
The answer
The full-moon festival is held every, you guessed it, full moon. Though drinking alcohol isn't allowed, you can find other ways of recreation, more on that later.
The spirit of this event is two-sides, the initial party is for socialization, and the end, like a COVID-19 quarantine, emphasizes on slowing down a little and spending time with close friends and family.
The most anticipated part of the festival is, of course, the feast. The feast usually ends at around sunset. The purpose of this event isn't just to have fun, you see, there are incense burners that help suppress the smell of humans and animals and have a mild calming effect. Similarly, most of the herbs that are used to spice up the food are normally used as sleep medication. The doses are low, of course.
So after the festival is over, everyone goes back to their homes lock up and go to sleep. Their tents tend to be sturdier than what humans use. Though these tents wouldn't be able to stop the entire tribe, they don't have to, they're mostly a safeguard to keep anyone who wakes up too soon from wandering off.
For monster hunters, attacking a tribe after full moon festival is still dangerous. You see, other than being tried for crimes against humanity, there's something else.
There are tales of monster hunters who tried to pull off such attacks but all of them went missing shortly after entering the forest. Later, they were found hanging from various trees and heights, kilometers away from where they entered, much to the joy of Logan Paul.
The ropes themselves were unremarkable. However, every single "victim" had an expression of fear on their faces, and judging by the dirt marks on them, must have been dragged to the tree.
The way their necks were broken also seemed strange. Rather than one big fracture, there were many tiny and medium ones. One can only imagine what could've caused it.
The more paranoid believe that the trees themselves came to life and had violently strangled the monster hunters, but then there's the mystery of the notes left behind, usually stuffed into a victim's bag or pocket.
This is what they say:
"Let them be and I let you be - Nooser"
