Salonia Carvain is a snobbish Imperial citizen who traveled all the way from Cyrodiil to participate in the wedding between Vittoria Vici and Asgeir Snow-Shod. She can be randomly encountered twice in the wilderness, before and after the quest Bound Until Death is completed.
She travels on foot accompanied by her husband Plautis and a single bodyguard. Due to their lack of knowledge about Skyrim, the group never makes it to the wedding in Solitude; instead they will end up inside the Temple of Talos in Windhelm, a long way from their destination.
When first encountered, Salonia's attire reflects her upper-class status and attitude, with fine clothes and matching boots. She carries a steel dagger and a selection of valuable gifts meant for the bride to be.
When approached, Salonia will be disgusted by your presence and reject you with: "Ugh. Speak to my husband if you must." or "Get away from me, you Skyrim trash." She will also be engaged with her husband, who clearly dragged her to the snowy province for personal benefit:
Plautis: "Come along, no more stops, we need to find our way to Solitude."
Salonia: "Why are we even going to a wedding at this far flung end of the Empire anyway?"
Plautis: "I told you, it's the wedding of Vittoria Vici, an extremely well connected merchant with the East Empire Company. The Emperor's cousin? Remember? Hopefully these gifts will put us in her good graces, secure that import deal, and lead the way to an audience with the Emperor."
After completing the quest, Salonia and her husband can be encountered again, although now in a miserable state. Her boots were ruined by the long walk, and she now walks around barefooted. When approached, she will be just as patronizing as before: "Ugh. It's talking to me.", "I hate this place. I hate the trees. I hate the rocks. And I hate the snow." and "Clearly you have no idea who I am you or you wouldn't dare approach me." Additionally, the bodyguard will no longer be present and Plautis and his wife will be on their own. Listening to their conversation reveals why:
Salonia: "I hate it here. Those were my favorite shoes, ruined and for what? We never even made it to the wedding."
Plautis: "Wha... Your shoes? We get robbed by bandits, my clothes torn to shreds by some giant cat, our bodyguard eaten by a dragon... And you're worried about your shoes?"
Salonia: "When we get back to Cyrodiil, I swear I will hire an army of battlemages to come up here and set fire to the whole damned province."
