NAGA
Udyana, in modern Pakistan, was famous for its water dragons. This is a story of one of those dragons.

The Naga are thought to be semi-divine snakes with human faces and serpents tales. It is in the Patala, a watery region under the earth that they reside.

It was by his subtle but powerful charms that the Naga Apalala was able to keep the wicked dragons in check. He prevented them from scourging the countryside with violent rainstorms. Asian dragons are quite often associated with the life-giving waters. Thanks to the Naga Apalala this countryside prospered and the grain grew thickly. In gratitude each family offered him a bit of grain as tribute. After some time several of the inhabitants of the place began to forego the yearly offering. The Naga became angry and prayed that he might become a poisonous dragon so that he could drench the countryside in rain and wind. So it is that at the end of his life he became the dragon of that country. To this day Rajas (local princes) in the Hindu Kush are said to be able to control the elements as their influence over local dragons provides.
