Born in Salm, the capital of the duchy with the same name, in the province of Ebbing, he only held the title of Duke of Salm. Therefore, when he was approached to marry Queen Calanthe of Cintra, he didn't hesitate to accept, despite all the weird relationship rumors about the queen, as it was a step up from his title as Duke. So when he was 24 years old, they married and he became king of Cintra. To hide the fact that Roegner wasn't royalty by blood, he was then referred to as Roegner of Ebbing.
In 1237, two years after he married Calanthe, Roegner was hunting in Erlenwald and got lost. As he wandered around the pathless tracts, he fell from his horse into a ravine and sprained his legs, leaving him immobile at the bottom of the gully. He tried calling for help but was initially answered only by predators but luckily for him, Duny found and saved him. As a reward, Duny then invoked the Law of Surprise which promised him "whatever he [Roegner] had left at home without knowing or expecting it." Pavetta was born later that year who would become Duny's reward.
Some gossipers believed that if Calanthe couldn't produce a male heir, Roegner planned to poison his wife and then take a younger, more fertile princess as queen. However, none of this appeared to be true concerning the couple.
Around 1246, at age 35, he passed away to the plague (or smallpox) and was buried in the royal crypt beneath the castle.
