Facial characteristics, skin colors or even size are not bound to race, but depend on the fable or legend from which they come. Still your size cannot be smaller than Tiny or larger than Large.
Your walking speed is 30ft.
Fables do not age, but they can wither into nothing if they are forgotten. Their lifespan is directly related to people who believe in them. It takes some time for a story to be considered a fable and for a fable to be born from it, but once they do, as long as one single person believes in them, they can stay alive. If a fable is killed, their corpse will disappear after an hour. Somewhere, they will be reborn without any memories, as the story is still alive, even if the avatar of it died.
You are considered fey in nature.

Due to their magic, a strange sense of familiarity washes of a person that grew up hearing stories about the fables, even if they don't recognise you. Fables have an advantage in Deception, Intimidation, Performance and Persuasion skill checks if they are used in response to or against people who believe or have believed in them before. 

Fables get an additional cantrip related to their story (the story which they originate from), either related to any other class or one of the player's choice (previously consulted with the DM).

The fables are traceable by methods of detecting magical objects. Arcane nullification effects negatively affect these beings to their essence. Effects that nullify magical properties cause them to fall to the ground, without forces to move and without magical abilities. Being the target of dispell magic or similar effects may cause you to become stunned and drop to the ground prone. You have to make a constitution saving throw when affected (of DC equal to the caster's spell DC) to be able to move again. You may try and succeed each end of your turn.

Despite that, they themselves can detect magic 1 time per long rest in an area with 30ft. radio. Once you reach 3rd level, you may do it twice, and when you reach 5th level, thrice per long rest.

Fables can change their appearance and size (by one category below or above their usual one) for 1 hour once each long rest. This is not considered a spell, but rathera racial trait. At 7th level, you may do this twice per long rest.

An ability score of your choice increases by 2, and a different ability score of your choice increases by 1.

You can speak, read, and write Common and one extra language of your choice. Fables typically learn the languages of other peoples they deal with, which are usually the ones that originated their story.
