The in-game help section, seen in the article above, begins with the words "Dwarves (using the V in the plural seems to have originated with Tolkien)..."

Basically, in English, you use "Dwarfs" when referring to stars and other things ("red dwarfs", for example), and "Dwarves" when referring to mythological short underground dwellers.
