The Stars of Fate
The wall of fire swelled like a tsunami, swelling a hundred feet in either direction. Plumes of fire cascaded before the wall, winding like serpents around houses, trees, and fallen corpses, reducing everything they touched to ash. Billowing waves of heat bore before it all, lighting countless fires in the brush long before the brunt of the spell arrived.
The spell's strength transcended the peak of fifth level, as far into the depths of sixth as possible without technically breaching the border. It was a true masterpiece of magic, possessing the skill and refinement of many of my modified spells. Had this terrible power not been directed at me, I would have loved to watch and study the flow of mana, for there was surely much to learn.
