Other social groups such as Vellalar have their own caste legends as to how they came to settle the east. Vellalar consider themselves to be the descendants of soldiers of Kalinga Magha(reigned 1215 - 1236), who invaded Sri Lanka. Curiously he was also considered to be instrumental in creating the Jaffna Kingdom in the North according to Yalpana Vaipava Malai and other scholars. Magha was an invader from present day Orissa state in India who recruited his soldiers from South India. His invasion is credited by Sri Lankan literature as one of the main causes for the failure of the classical Sinhala Dry Zone civilisations.
