Hey,
I'm watching Catching Fire right now, and I was thinking about this. We know what happens in the 75th games (Third Quarter Quell), We know what happens in the 50th Games (Second Quarter Quell and Haymitch's games) and we know what happens in the 10th Games (Lucy Gray's games). But we don't know what happens in the 25th Games (The First Quarter Quell), all we know is that the districts voted for the tributes. According to fandom wiki Coriolanus was president - no surprise there! We don't even know who the victor is!
