Anna was already on the edge when the earth began splitting open at the area where she was fighting against the Mercenary soldiers, but when a massive shockwave came from the central battlefield, carrying with it dust and debris and lots of small rocks travelling at insanely high speeds she knew that some real heavyweights were fighting in the middle and if she did not want to die a futile death it was best to retreat.
Apparently the Mercenary soldiers had the very same idea as both sides unanimously decided to disengage and run for their lives after the first shockwave arrived.
It proved to be an extremely wise decision as just mere moments later the entire sky turned starry and a devastating divine attack was launched near the centre which was countered with a seemingly equally powerful move causing a massive explosion to take place.
