In Skyrim, Rin is a character involved in the Creation Club quest called "The Unquiet Dead," which takes place at Goldenhill Plantation. During this quest, you discover that Rin ran away from home to escape his parents' constant fighting. His parents, Urval and Jonquil, tragically killed each other, each believing the other was responsible for Rin's disappearance. Rin's remains are found near an old well surrounded by wolves, along with his beloved toy sword. To complete the quest and bring peace to the spirits, you must find Rin's body, take his toy sword back to the plantation, and confront the ghosts of Urval, Jonquil, and Rin

. Thus, what happened to Rin is that he ran away due to family strife, but ultimately died near the old well at Goldenhill Plantation, which is uncovered during the quest.
