The story of the southern migration of the Vēḷir from Dvārakā under the leadership of Agastya is narrated by Naccinarkkiniyar in his commentary on Tolkāppiyam (pāyiram ; Poruḷ. 34). According to this legend, the gods congregated on Mount Meru as a result of which the earth tilted, lowering Meru and raising the southern quarter. The gods thereupon decided that Agastya was the best person to remedy this situation and requested him to proceed to the South. Agastya agreed and, on his way, visited Tuvarāpati' (Dvārakā) and led the descendants of neṭu-muṭi-an|n|al (Viṣṇu or Krṣṇa) including eighteen kings, eighteen families of the Vēḷir and the Aruvāḷar' to the south, where they settled down clearing the forests and cultivating the land.
