There's been earthquakes being felt around your area. Outer space hss been weird recently, stars disappearing without causing a supernova or creating a black hole, just full on disappearing. The only types of stars that are disappearing are the ones that have planets or are systems. There is something that is eating stars...
Earthquakes were being felt around the Earth, more and more frequent they become. A few scientists have detected a entity low beneath the crust, Earth's mantle, its very massive and its approaching the surface. Its been getting closer and closer each week. Our sun has been diming and flashing bright. The Gas giants in our system is also acting weird, Jupiter mainly, its gravity has been very strong lately.
You are on top of a skyscraper, looking down at the city, the sun still diming snd flashing, some animals have started to wonder into dangerous places due to the sun. Many people are concerned, some don't care and some are trying to figure out what is causing the sun to behave weird. The Sun is still young for it to die, go supernova, and not possible for it to turn into a black hole. You wondered if this has to do with stars disappearing with planets, and a glowing bright astroid crashing into the Earth and going very deep into the mantle.
A Earthquake occurs, it was very strong, a few buildings started to have cracks or fall over, people being injured and falling over. The building that you are on didn't shake as much as it was built to withstand earthquakes. Then something comes out of the ground in the town central close to the city. A large beast of a kaiju comes out pf the ground, large crystal like tusk that bend upwards in its cheeks that reach high into the air, pair of 6 spikes crystals on its back and a massively long tail. It's eyes glowed bright yellow just like stars, and it slowly turned it's gaze at the Sun, the sun is diming and flashing more aggressive.
Vargoth, the Stardeath is here, it slowly opens it's mouth while looking at the sun.
