Kartikeya's influence spread far and wide, reaching the southern parts of India, where he is known as Murugan. There, he became a major deity, especially in Tamil Nadu, where grand temples were built in his honor, such as the renowned Murugan temples at Palani, Swamimalai, and Tiruttani.
Legends speak of Kartikeya's journey to these regions, where he vanquished several local demons and protected the devotees. His devotees celebrated his festivals with great fervor, particularly Thaipusam, which marks his victory over the forces of evil.
