Nilotic al-Ourouba

Nilotic al-Ourouba was the probable original home of the Zensunni, the Misr. Nilotic al-Ourrouba is likely referring to the name of a location on Old Earth, encompassing the areas of Egypt, the Nile Valley and maybe some additional areas of North Africa, and/or the Middle East.

Behind the scenes
"Nilotic" refers to the Nile river and "Al-Ourouba" literally translates as "the region", hence it can be translated as the "Nile region."

In Children of Dune, this is confirmed as Leto and Ghanima speak to each other in Egyptian.
