Natural portals

Faster than their magically induced equivalent, these portals don't need receiving installations or a reference point to work. It's a pity that so many of them don't care about where you want or need to go, or how desperately you need to stay right where you are.
They are formed by all sorts of Shards related with travel and tourism, gathered by a core shard that comes from the lost freedom of an adult person. More often than not, this lost freedom had been used to hurt others one way or another. Even when there are cases where the person who lost it, the shard and the portal are all benign, it's advised to always avoid these ghosts and the areas of the forest where their presence if frequent.
The latter is easy enough, all those places have the proper signals to warn you. Predicting the appearance of portals in other places, though, is impossible. You will be lucky if you see them in time.

Basic Information

Anatomy

They usually look like a flash of light, which blinds their targets right as they are teleported to a random place. Only in rare occasion, they had been seen in the form of a door, stairs, or some kind of flying animal.

Dietary Needs and Habits

Biologist are convinced that these ghosts feed on the energy produced in the teleporting process, although there is close to no evidence about it.

Biological Cycle

Most Portals change with seasons, not to survive but to blend. In most of the premises, this means that they can change their color and shape when they entered an area with a different season, but there are some places where portals may go through all phases of matter during each day.

Additional Information

Social Structure

Sometimes, they are organized in such way that up to fifteen of them will create a chain of sorts by sending their victims right to the place where the next of them waits.

Domestication

Some have tried, nobody had succeeded.
These creatures would work better than Manufactured portals, but they are definitely not reliable, even if you could find a way to interact with them, how would you trust them?

Average Intelligence

While they don't understand the world the way we do, they are certainly better at math that any of us, and there are reasons to believe that they don't just blend in the environment by instinct but with the conscious intention of sneaking up on people.

Perception and Sensory Capabilities

Portals, natural or not, are capable to perceive every place of a world at the same time, as well as the physical composition of beings of different kind. Those are considered there sense of touch.
They are thought to lack of other senses, yet legends and rumors have been told that differ, and scientist admit that there is a possibility that different portals present different sense, especially those according to their appearances, when they take the shape of animals from their origin worlds.

The source

Many civilizations have restriction of movements as a mean of punishment, or as part of a security system. This means that people who has attacked their peers, broke the law, or somehow endanger other people or themselves, may lost their freedom by law. Maybe more frequently, people hurt themselves by irresponsibly using their freedom, and end up unable to go where they want, or even to communicate in their preferred way. Those are the kind of situation in which the pieces left behind end up founding a portal. We don't know why this doesn't occur naturally with the shards of other forms of lost freedom.

Behaviour and personality

Just like it happens with all species, each individual have its own peculiarities. With many ghosts, that depends on several factors related to the owner of the lost thing their core shards come from, the nature of that thing, and the environment in which they live. That said, Portals usually come from similar minded people and similar grief situations, therefore they have a few things in common: the constant interest on play tricks to others, and complete lack of respect or understanding of rules and personal limits, By general rule, they fall in the category of tricksters, having their fun by teleporting well dressed people into a swamp or taking those that are in a hurry to the very beginning of the path they have finally walked through. Others are more dangerous and may put people in mortal risk just to see them struggle for their lives.
