I should list some notable authors. For traditional kambikathas, names like Chavara Ayyappan Pillai come to mind. He contributed to religious narratives. Then there's M.K. Sanu, who wrote the famous 'Amaran,' which is in the kambikatha style. Also, C.V. Katta might have written similar works. For modern authors, I might need to look into contemporary Malayalam writers who adapt traditional forms into modern stories. People like M. Mukundan or Vaikkom Muhammad Basheer could be examples, though not directly kambikathas, their works are in similar narrative styles.
