The fuel tanks of liquid hydrogen for the fusion generators detonated, sending out a death cloud of shrapnel toward the damaged city below. Overloaded, circuit breakers exploded into molten metal, power relays slagged solid and the superconductor cables heated to the point that they ignited their own fireproof casing. Soon, billowing clouds of poison gas were added to the chaos. Busbars hissed into nonexistence, then the mighty fusion reactors exploded and melted. Gigawatts of stored power were released, and blue lightning crackled over the wounded arcology, setting fires everywhere that were promptly extinguished by the flooding from above and both sides.
