Ranmir is a male Nord living with his sister Birna in Birna's Oddments, a shop in Winterhold. After his lover left him, he became a drunk. He spends most of his time at the local inn, The Frozen Hearth, drowning his sorrow.
The innkeeper asks the Dragonborn to find out what happened to his lover, Isabelle Rolaine, because he doesn't like the state Ranmir is in. Talk to the people at the inn and find out that Vex, a thief in Riften, knows more about Isabelle. Talking to Vex reveals that Isabelle wanted to make some money from stealing, but she wasn't very good at it. Vex then sent her to Hob's Fall Cave. Isabelle's body is there along with a letter written for Ranmir explaining her intentions.
Take the letter and give it to Ranmir to give him closure on his lover's death. After receiving this news, Ranmir no longer tries to drink himself to death. Note that this quest has no monetary reward, but does count towards helping the people of Winterhold (Hold) in the process of becoming Thane.
Haran may also give a side-quest to convince Ranmir to pay his bar tab, which can be done with speech challenge, or by offering to pay the tab for him. Haran might give the quest even if Ranmir is dead.
It is possible for him to be killed during the College of Winterhold questline. During the fight with Ancano to neutralize the Eye of Magnus, the Magical Anomalies attacking the town may kill Ranmir. He may then be reanimated by Arniel Gane during the fight with the anomalies, after which, assuming he isn't re-killed, he will proceed to go into his house, and turn into an ash pile at the door.
