The descendants of Pandya dynasty discarded by Thirumala Naicker Diwan of Raja Vijayanagar, who was then ruling the Pandya Kingdom, comprising of Madurai,Tirunelveli, Ramananthapuram, were living scattered in places like Valliyur, Tenkasi, Shengottah, Achankovil and Sivagiri. At that time, Pandyas were ruling in many parts of Travancore. The descendants of Pandya dynasty belonging to Chempazhanattu Kovil, living in Sivagiri were given the right to rule the country of Pandalam, by the King of Travancore eight hundreds years ago. King Rajasekara was the direct descendant of this dynasty

King Rajasekara was very talented, courageous and just in his deeds. People were living happily and prosperously during his regime. However, the king was very unhappy that he had no children and his subjects were also worried that he had no heir to inherit his kingdom. As per the wish of the queen, both of them prayed Lord Shiva for blessing them with a child.

Mahishasuran, Son of Ramban, undertook a severe penance (Dhavam). Lord Brahma tried to distract his concentration, but having failed in his attempts, he appeared before the Asura and blessed him with a boon. Mahishasuran asked Lord Brahma to give him a boon by which no man in the earth would be able to kill him, and Lord Brahma conferred the boon on him.
