Although elves reach physical maturity at about the same age as humans, the elven understanding of adulthood goes beyond physical growth to encompass worldly experience. An elf typically claims adulthood and an adult name around the age of 100 and can live to be 750 years old.

Elves love freedom, variety, and self-expression, so they lean strongly toward the gentler aspects of chaos. They value and protect others' freedom as well as their own, and they are more often good than not.

Elves range from 5 to 6 feet. 

Accustomed to twilit forests and the night sky, you have superior vision in dark and dim conditions. 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.

Elves don't need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is "trance.") While meditating, you can dream after a fashion; such dreams 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 can speak, read, and write Common and Elvish. Elvish is fluid, with subtle intonations and intricate grammar. Elven literature is rich and varied, and their songs and poems are famous among other races. Many bards learn their language so they can add Elvish ballads to their repertoires.

As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see. Once you use this trait, you can't do so again until you finish a short or long rest.

At the discretion of the Dungeon master any deep emotional experiences, overwhelming trauma, or the first day of a new season may either trigger the subclass change at that moment or after completing the characters first long rest after the event.  The seasonal subclass may be changed to the next season in the cycle or rolling a d100 on the following Tables:

1-16:Spring;17-32:Summer;33-48:Autumn;49-64Winter;65-82:strong emotion;83-100:Current Season.
Correlate the emotions to the closest emotion. Joy:Spring; Anger:Summer; Fear:Autumn; Sadness:Winter.

If they are able to caste magic and have access to Cantrips then half of the number of cantrips rounded down/up are selected by the player; the rest by the dm.

Player cantrips are based on the current Eladrin subrace (Spring/Summer/Autumn/Winter) where the player may change the damage type (nature damage types) or shift the spell effect entirely.

Dm selected cantrips will be effected and shifted to fit the nature or season the character is experiencing.
