SUMMARY
The story revolves around Vandiyathevan, a charming, brave and courageous young man who sets out across the Chola land to deliver a message from the Crown Prince, Aditya Karikalan, to the Emperor Sundara Chola and the Princess Kundavai.
The antagonist of the story is Rani Nandhini.
- Rani Nandhini: Pazhuvoor Princess and wife of Periya Pazhuvettaraiyar whose birth and origin was doubtful in the beginning. The main antagonist of the story. She was born in Madurai and grew up in a priest family along with royal children in Pazhayarai until her youth. She is the foster-sister of Azhwarkadiyan Nambi. She hated Kundavai as Kundavai was jealous of Nandhini’s beauty. Nandhini and Prince Aditya Karikalan developed a liking for each other in their childhood which nobody in the royalty liked. She was forced to flee Pazhaiyarai and live in Madurai. After Aditya Karikalan beheaded the injured Veerapandiyan, Nandhini joined Pandya conspirators and vowed to avenge Veerapandiyan’s death by killing Karikalan and destroying the Chola dynasty. By marrying Periya Pazhuvettaraiyar who had lusted for her and by using him, she helped the Pandya conspirators. She had a deep hatred towards the Chola royals for their ill-treatment and also had a desire for the throne. She had a terrible childhood that affected her badly and wanted to be with her mother Mandakini. Parthibendra Pallava and Kandanmaran fell for her beauty and she used them for her plot too. [Mandakini Devi went to Thanjavur (while she was pregnant), Sembiyan Maadevi was pregnant too, so she took care of Mandakini during her pregnancy. During child birth Sembiyan Maadevi gave birth to a still born son but Mandakini gave birth to twins – a boy (Madurantaka) and a girl (Nandhini). Sembiyan Maadevi swapped her still born son with Mandakini’s son. She asked Vaani Ammal (a maid in the place at that time) to bury her still born son and gave the daughter to Azhwarkadiyan’s parents. After leaving the palace, Vaani Ammal notices that Sembiyan Maadevi’s son (Senthan Amuthan) is alive. She fosters him and raises him as her own son.]
