About Ahi / Vritra / Vrtra
Ahi was a huge, greedy dragon. He drank all the waters of the world and then coiled on top of the mountains. There, the Naga held all the water, unwilling to return it to the earth, which badly needed it.  The god Indra then attack Ahi with lightning bolts. After Indra slew Ahi, the waters returned to the world. 
Ahi symbolizes drought. When the spring comes and melts the mountain's snow, the water comes down much as it does in this myth.
Ahi was an enormous Naga.
