Mystery and Prophesy
Mystery and Prophesy can be used as many times in a game as the Scion has ranks in the Purviews. Which means a Scion with Mystery 3 can utilise the power three times within the same story.
In keeping with the Aesir theme, any uses of Prophesy reveal the future as it will be, not “as it will be if the Scion doesn’t change it”. What is seen is set in stone and cannot be changed. This does not mean that the Scion cannot use the information seen for his or her own benefit, but try as s/he might, the Scion is unable to change what has been forseen.
