Adela was one of the three children, later known as the Houtborg triplets, born when Riannon, queen of Temeria, was imprisoned by Falka. After Falka died, none, including Riannon, who went insane, knew which of the three children were Riannon's twins and which was Falka's. The sorcerers summoned by king Goidemar found out that Adela was Falka's daughter, but they told the king that they weren't able to determine which child was Falka's, to avoid a scandal and an execution of a 2-year-old child. Therefore, she was brought up together with Fiona and Amavet.
During an outbreak of Black Death plague she helped priests in a hospital and died from it at the age of seventeen. Her body was burned alongside the other victims of the plague. After her death, King Goidemar renamed the hospital after Adela, he also arranged a little monument of his (step)daughter.
