Do the names Odin, Landis, Byzantium and Corsica in the novel Hunting the Country really exist in history? If so, where are they?

1: Odin: Odin is the highest god of the Nordic ASEAN family, and is regarded as the king of gods, the king of death, the god of war, the god of power and the god of magic. He once ventured into the underworld alone, obtained ancient Chinese characters for mankind, and thus possessed a lot of knowledge, thus losing an eye. So Odin is not a place name.

2. Landis: There is no such thing. There is only one American star named Landis, and I don't know the rest.

3. Byzantium: the name of an ancient country. China's historical records call it Daqin, also known as Fuxi or Haixi Prefecture. In 395, the Roman emperor? China is divided into two parts. The Eastern Roman Empire is centered on the Balkans, and its territory includes Asia Minor, Syria, Palestine, Egypt, Mesopotamia and parts of the South Caucasus. Constantinople, the capital, is the former site of the ancient Greek immigrant city of Byzantium, so it is also called Byzantine Empire. This is an empire that really exists in history.

4. Corsica: Corsica is an island of France, located in the southeast of the French mainland, facing the Italian island of Sardinia across the bonifacio Strait in the south. It covers an area of 3,352 square kilometers. The population is about 230,000. There are many kinds of people vying for control of this island in history. 1768 was secretly incorporated into French territory. Corsica is now incorporated into France and becomes a large area. It is located on an island in the Mediterranean Sea (Corsica). It covers an area of 8,680 square kilometers and has a population of 270,000. In order to soothe the national pride of the local people, France has given them a special status in name and enjoyed the so-called autonomy. Actually, it's called Corsica local administrative region (Collectivité? Territorial? De? Corse), not the general area. It consists of two provinces: South Corsica and Upper Corsica. The seat of the district government is Ajaccio, the birthplace of Napoleon.
