On the few moments before explosion, the core starts to collapse in on itself, something that usually happens when any star goes supernova, however, this isn't any star, this is the Core of The Anvil, a much more powerful artifact, almost instantly a wave of interference lashes out outwards from the core, deactivating any and all equipment within the system, including the unmanned camera drone that now floats dead surrounding the collapsing anvil.
As if that wasn't enough, the pull of the collapse wasn't restricted to the core itself, it also affected the whole system, the close-by star deforms into an eliptical shape, like a drop of water a stream of plasma seems to be sucked in towards The Anvil, upsetting the gravitational pulls of the surrounding, gravitating everything towards the epicenter of the detonation, including the fleet that foolishly stood nearby, their portal proved useless for it was not attacked from the front, but deactivated and pushed from the back by the weird influences of the core, leaving the fleet completely exposed and deactivated for the detonation of the core.
Inside of the Anvil however, the Forge Master struggles to keep his footing witnessing the core spin and fluctuate like a tornado had passed over a once calm lake, his grasps his staff firmly, the staff seems to be absurdly stable and mitigating almost all of the effects of the core, it creates a triangular section, like a slice of cake, of the megastructure that, in the eye of the storm, stays mostly unnaffected, but what was to come was devastating.
For about ten seconds the core itself turned a shade between grey and black as the white sphere seemingly turned in on itself, it glew an indescribable color that emanated a gradient of a kaleidoscope of colors akin to a prism, that then collapsed into a white the more outwards it went, a deafening whistling sound was displayed as everything seemingly levitated for a few seconds, it was, to whoever witnessed it, a true momentary bliss, the calm before the storm. Then it becan to oscilate, like sound hitting water, it did so increasingly violently, until it eventually met its last fate, the collapse.
In a matter of tenths or even hundredths of a second, the black sphere bursted violently with the strengh of aproximatly 5000 FOEs, akin to half a Hypernova, the resulting luminosity was enough to vaporize the Forge Master, even protected by the staff, down to his bones, and carved an atomically perfect cake slice out of the megastructure, protected by whatever strange effects this staff had.
The rest of the megastructure wasn't so luckly, the force of half a hypernova made sure that everything but the farthest pieces of the megastructure were instantly desintegrated converted into a dense mix of gas that once was metal and flesh. The fleet and the drone outside would see a flash of light so bright and with a burst of radiation so immense that the surface metal of the ships would instantly melt or turn to gas, the crew would immediatly break down into a soup of de-organized cells with completely shredded DNA, quite litelary turning into jelly, and the electronics would immediatly fry themselves due to the radioactive interference of the burst, not to account with the core supernova interference, that'd turn mad any crew that was within the system, had them not died due to possibly the most acute case of radiation poisoning in the history of the universe.
However, only about 1% of the explosion is the visible light, the only part that stood somewhat safe was now completely ellapsed by the radply expanding gas from the vaporized and desintegrated megastructure, its devastating wave first hit the star of the sytem, that splashed as if it was a baloon bursting when hit by an tremendously fast bat, shaping itself to the radius of the expanding gas bubble, until the chaos theory took over and sent its plasma united with the plasma of the detonation outwards into the nothingness, to heat up the cold universe. The following were to be the drone, which was so minute that it immediatly turned into a pancake of metal, then due to the sheer heat of the plasma it turned into a boiling mix of metal, then plasma united with the carrying wave. The fleet though, was larger, but was not luckier, they were exposed and even if their shield had worked the sheer strenght of the plasma kinetic wave and heat of it would melt away anything that was mildly close to the edges of the portal. The expanding wave hit them nonetheless, flattening all in the circular shape of the expanding sphere of the explosion, making ship crash into ship only to be engulfed in the hottest of flames within the universe, quickly vaporizing any material that was still metal, it was a mercyless death to which no songs would be sung.
However, this explosion had many ripples across all of space, it was felt by almost everyone, to most it was ignored, but some things took notice, some beings knew the light that would come, some others cried in despair or in joy, one particular entity, struck by it, awakened.
