Heroes of rokugan season 1

[meroooooo]

Hi, I have been mastering L5R for a long time (since 2nd edition to 4th today) using the storyline of "heroes of Rokugan season 1" set in the alternative clan wars.
Now, after years of playing, I am nearing the end of the campaign. I don't wan to miss the big ending for my players but the problem is that I never managed to find the last few mods of the campaign (missing "unmaker's shadow", "dragon's heart" and "day of thunder").
Did anone in here play those mods ? If so could you tell me what happens in the "official" campaign ?
