Influence Character Unique Ability
the item that makes the Influence Character uniquely able to thwart the Main Character
This story point represents the Influence Character's unique ability to force the Main Character to change his or her paradigm. In much the same way that the Main Character Unique Ability reflects the quality that allows him or her to effect a resolution in the Objective Story Throughline, the Influence Character Unique Ability reflects the quality that allows the IC to effect a resolution in the Main Character's Throughline. The Unique Abilities tie the individual Throughlines to one another; the IC Unique Ability ties the Influence Character to the Main Character.
The reason the Influence Character is able to carry half of the Relationship Story is his unique suitability to take the opposite position to the Main Character on the Crucial Element of the story. The Influence Character Unique Ability gives the Influence Character a power which no one else in the story has to be able to affect the Main Character. The nature of this power is what is described by this appreciation.
