From publisher blurb:
An Ultima Forsan short campaign in three Episodes for three to six Novice or Seasoned characters.
The Heroes are recruited to find an ancient relic of great political and symbolic value: The Iron Crown. This ancient crown is said to contain one of the nails of Christ’s Cross. Due to its history, it also represents the ideal of a unified kingdom of Italy.'
If the characters have already played the free adventure "The Confessional of the Black Penitents", this campaign could be played as a sequel, and the Podestà of Modena happily entrusts them with the task.
