How many races are there in interstellar space?

TERREN (Terran): The alien migration experiments conducted by the United Forces of the Earth are basically criminals. The Tyrone Federation in SC 1 has fallen, and the Tyrone Empire (Tyrone Autonomous Union) in Grosmensk, Aktug has been established. Of course, there are also troops such as Renault Commando, Kyle moria Company, Yumoje Protector and Freedom Mercenaries.

PROTOSS (God's people, spirit): The first race created by the biological race Xel'Naga in the universe, with strong spiritual strength and extremely developed technology, but low fertility. The planet of origin is Al (occupied by the Zerg), and the main star is located in the hometown of the Dark Templar-the planet Sha Kelas.

ZERG (Swarm): After the great division of the protoss, Sanaga abandoned the protoss and went to the volcanic planet Char to create another race. With the ability of self-selection and rapid evolution, it can adapt to almost any environment. The biggest feature is the number of lower zerg.

PS: Naga is an ancient upper-level elf who was corroded by the ancient gods in warcraft 3, and now she is a distant relative of the night elf.
