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 the year 1235, the same year he married Calanthe, Roegner was hunting in Erlenwald and got lost. Wandering around the pathless tracts, he fell from his horse into a ravine and sprained his legs. He lay at the bottom of the gully and called for help be but was answered only by predators. He was saved by Duny and as a reward, according to the Law of Surprise, promised him "whatever he had left at home without knowing or expecting it". Two years later, Pavetta was born and 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.
