Zzzap’s energy fighting Midknight’s energy

The wraith forced his way higher into the black air. He willed himself brighter and pushed out against the darkness. And again, the shadows resisted.
They pushed back hardest from the northwest.
Zzzap flew past Bee and the gate. He shifted in the air and let off another burst of light. Below his feet the black parted to reveal thousands of exes clawing up at him. They covered Gower like an open concert venue. The darkness rolled back and he resisted it again.
To the west.
Another burst guided him into the alley across the street. The consuming night had weight here. It pressed down on him, smothering his light like an ocean of ink. He let off enough energy to melt through steel and the shadows fled for a few moments.
