K'Larla is 29, born to a Betazed mother and Vulcan father. Despite what many assume, K'Larla is perhaps the most well-balanced and stable person she knows. Neither parent encouraged her to lean more closely to one culture or the other, and she grew up with a pleasant mixture of both. She has moderately pointed ears - enough to show she has some Vulcan heritage while also revealing that she is a hybrid. She has the dark eyes of a Betazed and a modest degree of empathic powers. K'Larla was an exceptionally cheerful and loving child and grew into a friendly and compassionate adult.

Her first name was an idea of her father's, her surname is that of her mother. She generally goes by the nickname of Kay, but her family and a few close friends call her Larla. She grew up on the Starfleet vessels where her parents served, but never had any desire to join Starfleet herself. When the opportunity came to run her own shop on Starbase 114, she was only to happy to take it. She has worked previously as bartender on several galaxy class ships, but was relieved to finally reach the relative stability of starbase life.

She currently runs a small beverage and snack cafe, but constantly changes the format and layout of the place. Patrons find things a little different each time they visit and the versatile little business hosts many curious events (from 'sand castle day' to 'life-size chess games'). K'Larla is of average height and is a just a little overweight (she believes in old fashioned cooking and bakes exquisite pastries - a hobby that has given her little hope of ever having her father's lean Vulcan physique). Her shoulder length hair is dark brown and she loves to wear bright colors. She encourages her employees to dress nicely, but doesn't require a specific dress code of them. K'Larla smiles often, making those around her feel comfortable and welcome.

Recently, K'Larla moved her shop to Deep Space 13.
