Dune Elf

Age. 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.

Alignment. 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.

Size. Elves range from under 5 to over 6 feet tall and have slender builds. Your size is Medium.

Darkvision. 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.

Keen Senses. You have proficiency in the Perception skill.

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

Trance. 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.
If you meditate during a long rest, you finish the rest after only 4 hours. You otherwise obey all the rules for a long rest; only the duration is changed.

Environment Adaptation. You have advantage on Constitution saving throws made to resist the effects of extreme cold or extreme heat.

Fleet of Foot. Your base walking speed increases to 35 feet.

Mask of the Sands You can attempt to hide while not obscured if you are in a sandy environment such as a desert. You have disadvantage on this Dexterity (Stealth) check unless you are at least lightly obscured by foliage, weather or other natural phenomena.

Languages. You can speak, read and write Common and Elvish.
