Hann or Hannu is a half-mythical land lying to the south of Nilfgaardian Empire along with Ofir, Zangvebar, and Barsa. Yennefer once mentioned the land while describing her powers. 
- In A Shard of Ice's translation, it is spelled "Hann" but other official sources spell it "Hannu". This discrepancy could possibly be due to a translation error.
- Name of the land is probably inspired by Hannu, an ancient Egyptian noble and traveler. During one of his travels, the traveler visited Ophir - the land of King Solomon's Mines, which name was an inspiration for another oversea country.
