In amongst deep, dry gorges and basalt plains south-west of Katherine in the Northern Territory, Wardaman people look after the Lightning Brothers, who are an important part of the land. They help bring the big rain and keep the country healthy. They come from the sky, but rest on a rock surface at Nimji on Willeroo Station. Their story is passed down from generation to generation. The Lightning Brothers are children of creator spirits frog lady Dungung and sky boss Nardi, and the brothers work together with serpent Rainbow Gorrondolmi to bring rain across the country. Jabirringgi brings the big rain called barrawunda with yarrindi, the song with power. Barrawunda means strong, heavy winds like a cyclone or tornado. The wind was given to Jabirringgi by the Little Grasshopper. In the rock art at Nimji, you can see the electricity, jirra, in his feet. He makes sheet lightning that reverberates the whole earth. His brother Yagjagula makes fork lightning with his two stone axes. He flicks them together making a loud noise and chips fly everywhere, striking trees and grass. Yagjagula’s sparks start fires that regenerate the land. The fires help keep the country good — they stop big bushfires, keep the rivers clean and help animals breed. Wardaman people deeply respect them and make sure they look after them, to care for their country. The Lightning Brothers are stars in the night sky (Centaurus), the law place in songlines, notifying Wardaman people that it is ceremony time for initiates.
