With this subplot the character actively looks for opportunities that give rise to stories of inspiration. Victory is not enough; the people must know who achieved this victory. Think of when Bruce Wayne returned to Gotham in "The Dark Knight Rises". He could have just slipped unnoticed into the city and used annonimity to aid his plan. Instead he covered one of the bridges in a huge burning bat symbol. That's the kind of action that create stories.
In addition to the award of one possibility at the end of the Act, if the player achieves or contributes to a Glory Roll, then all players receive an additional award of one possibility per Glory Roll. Furthermore, if the Glory Roll took place in a Dramatic scene then the action may be used as a Glory Deed if the GM so agrees.
