Assuming the authors math was correct (massive IF by the way) the impact would be the equivalent of 4.2×109 J Energy released by explosion of 1 ton of TNT. (https://en.wikipedia.org/wiki/Orders_of_magnitude_(energy))

THIS I HATE, the main story getting split for a sub story no body cares about, we dont care about another group of 'heroes' AT ALL

a level 35 mage 'dueling' a level 7 sage + what ever level jester he was, has no chance
