Your Dexterity score increases by 1, and your Charisma score increases by 2.

Come to think of it, you've never been to a feyling funeral. Sure there was that time you took nap in the casket of the chief hierophant of Tyr, but that's not really it. Dying of old age just sounds so tedious...

In the prime dictionary of candlekeep next to the entry for mercurial there's a picture of your face. Feylings are usually chaotic.

Feylings are always just the right height and are particularly svelte if they do say so themselves. Your size is Medium.

Your base walking speed is 30 feet. Your base dancing speed is just enough to clearly be the best in the room without looking like you're trying.

Your people have reveled in ancient forests since the stars were fresh in the sky, and the sun and moon were not yet born. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have proficiency in the Perception skill.

You have advantage on saving throws against being charmed, and magic can’t put you to sleep.

You don’t need to sleep; that would be such a dreadful waste of time. Instead, you enter reverie, meditating deeply and remaining semiconscious for 4 hours a day. While meditating, you can come up with 5 ways to indirectly imply to the Pasha that if he doesn't give you his favorite horse as a half birthday gift, spiders will steal his dreams. Such considerations are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

You know the old language, and the names of many things. The magic of your people comes to you like breathing. At 1st level you can cast the Minor Illusion cantrip. At 3rd level you can cast Faerie Fire once per day. At 5th level you can cast Suggestion once per day.

Being unable to lie outright has naturally made you a savant at all manners of distortion, evasion, obfuscation, and misrepresentation. You have proficiency in the Deception skill.

You can speak, read, and write Common, Sylvan, and Elvish. Sylvan is like birdsong and like thunder pealing across a meadow on a sunny day. It was trading secrets when Asmodeus served Mount Celestia. It is nefariously subtle, and the day you hear a human speak it well is the day you give up playing riddles.
