Despite having wilderness survival knowledge, Frisk chooses to remain in Athens to search for his sister. Sometime relatively shortly before he fell into the Underground, Frisk helped Artemis make a bow so she could survive off the natural supplies in the surrounding Hellenes Forest. Īt an unknown relative time, Frisk met a young girl named Artemis, who herself was also attempting to survive on the streets of Athens, along with helping her sister, Amelia, survive as well. Shortly after, Frisk was separated from his sister and never saw her again. Afterwards, William, Frisk's older brother, took care of him and Aliza, his younger sister, for the next 'fifteen years' before abandoning them both. At an unknown time, Frisk's parents were killed in an automobile accident. Not much has been revealed relating to Frisk's life before falling into the Underground.
