Olaf is a Springvale villager that has been frozen for the past 300 years by a Cryo Regisvine after chasing a boar into an underground ruin. The Traveler and Xiangling run into Olaf while looking for fresh ingredients, who was recently unfrozen. They give him hot soup to warm him up, and he returns to Springvale where he tries to get used to life in the future. https://genshin-impact.fandom.com/wiki/Olaf
