Shadowrun Mana Storms


i have been writing up some stuff for an australian source book for shadowrun 4a, here is the part on mana storms


Mana storms:

Mana storms are some of the most destructive things to ever happen since the awakening of the 6th world. Mana storms whip up the magical ebbs and flows on both the physical and astral plan at the same time, this often creates devastating effects upon both plans in the form of elemental and illusionary attacks. Because of their ability to be on both plains simultaneously when a Mana storm forms it also brings with it normal storms, whether its thunder and lightning or wind and dust, these effects come with the mana storm. These storms can last any where from 1 hour to weeks or even months at a time, they can also turn up out of the blue or build up for a long time, of course the longer they build up for the more powerful that they become.
