"Demon of the Abyss..."
Finally hearing these crucial words, Ian shook his head to calm himself: "Life existing in the event horizon? Simply inconceivable..."
The Star of the End is the Black Hole.
At the end of its life, a massive star's nuclear fusion can no longer counteract its own gravity, causing most of its material to collapse inward, forming a supernova explosion while creating a black hole at its core.
The black hole holds the majority of the star's mass, and at the Schwarzschild radius centered at this black hole, a 'layer' formed, isolating it from the external universe, known as the event horizon.
Even light, once it enters the event horizon, can never escape.
To beings like the Star Gods, embodiments of light, aside from choosing death themselves, only a black hole can give them a conventional sense of the end.
