A Lovely Letter

Love Triangle is a side quest in The Elder Scrolls V: Skyrim. It includes Faendal and Sven trying to win over Camilla Valerius.

Walkthrough
You can start this quest by either talking to Faendal or Sven. Talking to either of them will give them the chat interaction of asking about him and the other one (Faendal or Sven depending on who you talk to first) liking the same girl. They will then ask the Dragonborn to deliver a fake letter from the other lover. The player then has the choice to give Camilla the fake letter, or warn the other lover of the fake note. If you decide to give the note to Camilla, then she will fall in love with the letter writer, and will begin to dislike the other. But if you want to warn him of the letter, they will write a letter themeselves and will ask you to deliver it to Camilla saying it's from the other lover. The only option this time is to give the note to her. She then will fall in love with the note writer.
