Fate is a manifestation of the power of the collective unconsciousness of humanity to warp reality to match stories (if you’ve ever read Witches Abroad you’ll get know what I mean).
Characters with high Legend will have to contend with their Fateful Aura and with Fate-binding.
The Fateful Aura is the effect that draws heroes into stories- it manifests as strange or interesting events around the character. Calamities, miracles and strange or momentous events of all kinds happen around those with high legend; they live perpetually in ‘interesting times’ as the fateful aura attracts improbable events. For example, if there is going to be an armed robbery, it will happen to happen just as the character goes to the bank.
This neatly explains ‘PC syndrome’ in-game.
Fate-binding is the ‘gravitational’ influence of Legend- characters with high Legend find others drawn to their presence as Fate manipulates them to play a role in the story of heroes. People, places and objects can become entangled in the metaphysical threads of Fate that emanate from character, and the subtle influence of Fate will try to act as a puppet-master to make them play their rolls in the unfolding story.
This Fate-binding effect is one of the main reasons that gods generally avoid involving themselves directly with mortals.
