Homebrew Fetch (Doppelgänger) Species Details

True Form

To other races, the Fetch looks like the creature it was replaced with due the illusion placed on it by the Fey. However, their true form differs from most of the other creatures in the Material Plane. They range from under 5 feet to about 5'7 tall, and anywhere from 90lbs to 125lbs, with men only slightly taller and heavier than women. Fetch men do not have facial hair, but often have long heads of hair that drape down their backs. Fetch's coloration are often dull blues, purples, and greys.

Unknowingly Unaware

Because the Fetch is a direct result of the Fey's trickery and deception, the Fetch lives out the life that they were given; creating the version of the person that they've replaced in this manner, and more often than not, die without ever knowing that they are not real. 

Why do the Fey bother? With all their power, surely it's more expedient to just take people and leave their families to wonder? Over the centuries, Fey have occasionally tried simply stealing people and not bothering to replace them, but the Fey find that many creatures beings are persistent. Parents, especially, do not rest if their children are taken away, and over time, these obsessed people have found evidence of the Fey -- changelings, gateways, and so on. This is just one of the reasons that so many faerie legends persist, perhaps, is because of carelessness on the part of the Fey. Better to create the Fetch and let the creatures believe that everything is all right.

Exiled or Created

When being created, the Fey shape the Fetch out of a portion of the abducted creature's shadow and give it flesh made from materials that the Fey carry with them. After a few weeks masquerading as the creature, the illusion is solidified across into the Material Plane, so much so that even the Fetch's 'family' can't tell the difference.

However, some Fetch's are not created, but instead, are hollowed-out versions of a Fey that has been exiled from the Feywild. As punishment for their misdeeds, the Fey wipe the memories of the Exiled and banish to the Material Plane to live out their days as a mortal. While they now have the appearance of the creature that they have replaced, they can sometimes retain certain abilities from their time within the Feywild. Now being considered normal, more often than not, the abilities that they keep are considered works of evil or curses by the people around them, and if discovered they are used for dark purposes or put to death.

Finders Keepers

Fetches have no lands of their own, but since they take the form of the creature that they are replaced - they are welcomed within the society they are "born" into; as long as they are not discovered.  However, if a changeling (the creature who was captured) escapes from the Feywild and returns to the Material World, they have an adversary waiting for them -- the fetch that was given their life. 

Fetch Names

Fetch's are likely to have one of two types of names, the given name of the creature that they've replaced and one (if they were an exiled fey) that they had within the Feywild. The name they had before banishment is typically unisex and are very short usually one syllable.
