I still say there had to be a reason as to how he learned about Cadance.

She still made the decision to transfer her Alicorn magic to Twilight, and Tirek still sent her to Tartarus alongside Celestia and Luna, even though the Royal Sisters originally imprisoned him.

There had to be a way for him to learn about Cadance, even before confronting her and the Royal Sisters in the throne room in Canterlot, because he went after all three of them, not just Celestia and Luna.
