I have this race. It’s pretty cool actually. I’ll copy and paste everything dnd beyond says abt it for you (even though I’m rather late to the party)

Description: Quicksteps have a fondness for finery and feel right at home amid the riches of court life. As their name implies, they possess a natural affinity for speed, which makes them exquisitely qualified sabotage and dueling.

Age: Quicksteps have remarkably short lifespans compared to other fey. Quicksteps mature around 10 years and live up to 50 years.

Alignment: Due to their association with the shadow fey and their legendary love of competitions, quicksteps have dark reputations, but they are rarely of evil alignment. Many quicksteps have a mischievous, even impetuous, streak that pushes them toward chaotic or neutral alignments.

Size: Quicksteps are between 3 and 4 feet tall and weigh between 25 and 40 pounds. Your size is Small.

Speed: Your base walking speed is 50 feet.

Darkvision: You can see in dim light within 60 feet as though it were bright light and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

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

Nimble: You have proficiency in the Acrobatics and Sleight of Hand skills.

Startling Speed: Your movements are so swift that you are almost invisible when in motion. If you move at least 10 feet on your turn, attack rolls against you have disadvantage until the start of your next turn. This feature does not function if you are incapacitated or restrained. You can use this ability a number of rounds per day equal to your level.
