The Empress had no wind power even though she had a title that used the word wind.
This wasn't strange since she wasn't from the Sacred Wind Empire to begin with.
She was an outsider who developed her own cultivation techniques.
Her power is the power of creation. In other words, she can create anything with her mind.
Only, it was only limited to illusions. It might be more accurate to say that she was a user of the power of illusion.
Some people liked to over-praise to get attention, so they preferred to call the Empress a power of creation user.
In fact, the power of creation was almost like a fairy tale. Although it was said that it really existed, most people said that it was impossible because it was like mastering all kinds of powers.
