Fluff

Brighton is at the centre of a snap and random people manifest abilities. Distribution appears entirely random, though those at the centre of the snap are either consumed or destroyed by massively fluctuating abilities, they also lose seemingly all trace of personality and neural function, though manifest terrifying powers.

Further out from the snap, where the PCs are drawn from, powers manifest less hazardously, though in some cases suddenly. Variants caught in this middle ground display a safer and more stable power manifestation initially.

Those further out on a wider band receive minor powers, though it is observed that their health deteriorates. -Handwave explanation is that variants receive a parasite which is healthier and stronger towards the centre of the blast. At the centre it is overwhelmingly powerful and consumes the host, is stable at the safe band, and is parasitic and unhealthy furtherout-

Effects of power manifestation
 * Supernatural abilities manifest
 * Depending on subtype, bodily health is restored
