Catherine Ironfist

"Look. It's Queen Catherine. Now that she's brought to real life, I think this Tribulation stuff couldn't get much worse when she came here right now."

--Su Ji-Hoon, Erathian Union

Catherine Ironfist (née Gryphonheart) was the wife of King Roland Ironfist and daughter of King Nicolas Gryphonheart, whom she succeeded as the Queen of Erathia. She restored the Kingdom of Erathia from the brink of collapse after it was invaded by multiple sides following her father's death, and later played an instrumental role in the war for Armageddon's Blade.

The protagonist of Heroes of Might and Magic III: The Restoration of Erathia, she is voiced in all of her appearances, including the Korean drama, by Wendee Lee.

In When the Cold Breeze Blows Away, she is well known for changing the official name from the Kingdom of Erathia into the Erathian Union, and since she is the defender of her kingdom, and as Su Ji-Hoon and the Preschool Girls came to help her kingdom to turn itself into a modern empire, she eventually became allies with France, Britain, the USA, Canada, the Asian Federation, the NATO, and the rest of the Grand Alliance.
