I heard the champion is a master of winning games with oglop cards... Her name is... 'Erin the Oglop Master'...Treno resident regarding Erin.
Erin is a minor non-player character in Final Fantasy IX. She works with airships in Lindblum and accompanies Regent Cid to the Tetra Master tournament in Treno. She plays the role of the champion, as Cid is still an oglop at this time. Zidane's lines change while speaking to Erin and Cid after the card tournament depending on whether the player met Erin in Lindblum during the party's first visit there.
Later, she pilots the Hilda Garde III when the party uses it to travel the world.
