Antal is the Langurâpha word for "steps". This river was named for its hundred or so steps of granite and adamantine. Each of these is the start of a waterfall. In the early days when civilization reached the river's upper tracks, continuous travel down river was impossible. Along the river are the ruins of many bridges, cranes, and tracts for portage. These were built after the founding of Liope. They fell out of usage in the Dao Civil War.
