During his reign, he quarreled with Sasivarna Peria Oodaya Thevar of Nalukottai and drove him out of his Nalukottai Palayam. Consequently, Thevan, the brother of the late Sundareswara Regunatha Sethupathy fled from Ramnad and sought refuge with the Rajah of Tanjore Tuljaji. While Sasivarna Thevar was passing through the jungles of Kalayarkovil , he met a "gnani" (sage) named Sattappiah, who was performing Thapas (meditation) under a jam bool tree near a spring called 'Sivaganga'. The deposed king prostrated himself before him and narrated all the previous incidents of his life. In response, the Gnani whispered a certain mantra in his ears (Mantra Opadesam) and advised him to go to Tanjore and kill a ferocious tiger which was kept by the Rajah especially to test the bravery of men. Henceforth, Sasivarna Thevar went to Tanjore. There, he became acquainted with Kattaya Thevan a refugee like himself. Satisfied with the good behaviour of Sasivarma Thevar and Kattaya Thevan, wanting to help them to regain the states again, the Rajah of Tanjore ordered his Dalavoy to go with a large army to invade Bhavani Sankaran. Sasivarna Thevar and Kattaya Thevan at once proceeded to Ramnad with a large army furnished by the king of Tanjore. There, they defeated Bhavani Sankaran at the battle of Uraiyur and captured Ramnad in 1730. Thus, Kattaya Thevan became the 11th King of Ramnad.
