Penny's memory of life before Phandelver, the other defenders, and Leo is rather limited. She knows she had a mother and maybe some siblings but trying to call upon memories of them is futile. Leo found her in an ancient ruin she was surveying behind a locked door, and since then Penny has been living with Leo. Slowly trying to recover he memory and assist Leo in discovering what caused her to lose them in the first place. While in Phandelver she took up sewing and embroidery as a way to keep herself busy and her mind off of nightmares that were plaguing her sleep. After a few months Penny had settled in and started to consider Phandelver and Leo her home and her life pretty peaceful. Until that fateful visit to the apple thief's house and meeting the other defenders.

At first traveling with the other defenders was exciting and a great break from the calm of Phandelver. But after the parties first encounter and Penny awakening a deeper power in herself that had some gruesome (head exploding) consequences, Penny became more weary. Not of her new party members but of herself. Keeping the new developments a secret from everyone else, Penny hoped it would simply fade away like her memories. However, during the parties visit to Thundertree, Penny's powers grew in new terrifying ways. Suddenly faced with a bony monstrous talon growing from her wrist she tried her best to hide the new developments and rid herself of the new extremity. Unfortunately Leo discovered what was happening but quickly helped Penny hide from the rest of the party. Later the two had a heart to heart about the problems both of them faced and promised and promised to be completely honest with each other.

When the final confrontation between the Defendes and Glassstaff occurred, Penny tapped into some of her power in an attempt to heal Nevarra. But due to her inexperience she trapped a changelings hand in her stomach as she healed over the intrusion. Nevarra, who Penny was closest too has not been as warm since and Penny is becoming more and more worries. Additionally Valendor has voiced his suspicions to Alucard that Penny and Leo are covering up something strange…

As of season 2 Penny's powers have kept growing, and despite her and Leo's efforts, Naveara and Alucard have noticed something amiss. Penny

Leo has soft grey eyes and deep brown hair tied back with a red ribbon. Her face wears an anxious expression consistently, worry aging her face beyond her years. She is approximately 5'8“, of slender build, and 26 years old.

She is absolutely terrified of fire after being nearly burned alive in Iarno's magic shop. It almost got better until she witnessed Penny almost burn alive in Wave Echo Cave.
