Saba Colbshallow and his mother Yadira Colbshallow are characters in the Senta and the Steel Dragon series, beginning with Book 0: Brechalon.
Yadira Colbshallow is the Dechantagne cook and has served since she was quite young. She is a widow, with one son upon whom she dotes-- Saba. In book 0 and book 1, Mrs. Colbshallow is a minor character who pops up to offer advice or information.
Saba Colbshallow is one of the major characters in the series, though he occupies a very minor role in Book 0: Brechalon. When we meet him here, he has just turned 14 and is being given his first assignments in the household. Part of what I like so much about Saba is that he changes so much. He grows and changes and so he occupies a different role in each of the books.
