Did You Know: The prisoner that taunts you at the beginning of Oblivion, Valen Dreth, has a living relative in Romlyn Dreth in Skyrim? Romlyn will even speak fondly of Valen Dreth’s life with the innkeeper at The Bee and Barb:

Romlyn: “Have I told you about Valen, my dear?”
Keerava: “I love when you spin that yarn. Gets better every time you add something new.”
Romlyn: “He killed six Imperial Guards before they dragged him into the prisons.”
Keerava: “Was this before or after the Mythic Dawn attacked the Emperor and Valen single-handedly fought them off? Just shut up and drink, Romlyn.”
