Dune is about a lot of things, but the logline usually focuses on the endless feud between two noble families. House Atreides and House Harkonnen have a brutal rivalry that lasts thousands of years. While several members of both groups find other things to do, many representatives spend their entire lives trying to destroy their ancient enemies. Dune: Prophecy will explore one of the earlier chapters of this quarrel, depicting Valya Harkonnen's astonishing commitment to murdering every Atreides she can reach.
