Tall at 5' 10" and wiry, Rierdan has long blonde hair usually worn in a simple braid down her back. She has blue eyes, which can appear cold at times
Typically, she dresses in simple clothes in muted colours, her favourite and usual being brown. While Rierden often wears trousers in the field, she tends to wear long skirts when she has the opportunity.
Laura has a strong personality, which leans towards stubborness. She is highly driven, and has spent much of her life alone, or isolated from those around her, which means that she has developed an intolerance for people who do not follow her procedures.
She respects people with strong characters, even if she does not necessarily agree with their beliefs. She firmly believes in the chain of command, and will follow all but the most questionable orders from her superiors, and expects the same from her inferiors.
She has an owl, Norri, and a rather elderly and portly tabby cat nammed Binks who will slowly follow her wherever she goes. She has few posessions, her life in the field necessitating her traveling light.
Laura was born in Ireland to a respectable wizarding family. In 2020, at the age of eleven she began her education at Hogwarts. She was sorted into Ravenclaw and was generally considered by most to be a bright witch. While she excelled in her studies, she found her true interest lay in Ancient Runes.
In 2027, upon graduation from Hogwarts, Rierdan began work for Gringotts as a curse breaker. However, she found that the Goblins had limited interest in the areas of study that Rierdan preferred. She left the bank, joining a muggle Archaelogical expedition in Norway. She spent almost a decade with various teams before returning to the wizarding world, where she continued to review her findings.
When she heard that the position of Ancient Runes teacher at Hogwarts was open, she immediately applied, knowing that it would give her the spare time she needed to finish her research.
