If Lord Murugan is the "Tamil God," do the Telugus, Malayalis, or Kannadigas have their own unique regional god as well?

 In the history, there are three phases of revival of Lord Murugan worship.

First as a Lord of Kurunji or Mountaineous region of Tamils during Sangam Era. He is a Tamil God “ Seyyon”.

Second as a son of Shiva and Parvati, He is a God or Dev of Entire Subcontinent.

Third as a Kaliyuga Varadhan, a God of Kaumaram in peninsula region, since 15th century - to conquer and spread their dominance in SE Asian countries as well as to uproot Buddhism. Here rituals (laid down by a mystic sage Arunagiri Nathar patronised by Prauda Devaraya II) become important alongwith two consorts- Devyani and Valli & Vel. Here he is not only a God of Tamils, he is worshipped in Karnataka, Andhra, Kerala, Tamil Nadu and South East Asian Countries.
