The Choice of The Universe

The most powerful and advanced race in the Chaos universe has sent its state-of-the-art research ship into space to search for inhabited planets and, if necessary, colonize them.
Years later, on their way back home, their sensors caught a strange energy fluctuation coming from the black hole they passed near. Therefore, they changed direction and got as close to the black hole as possible.
At that moment, the lightning energy suddenly released from the black hole hit the research ship. The ship, whose all systems suddenly shut down, lost its balance and was pulled into the black hole. After a while, the ship started working again, but it was too late.
They could not escape from the black hole due to their insufficient energy, but sensors discovered that there was a wormhole inside the black hole. The ship heading to that point passed through the wormhole at the last moment and reached a very small universe.
When they began to examine the new universe closely, they were immediately spotted by the local races and a war broke out between them. They lost the war because their advanced weapons were useless in this universe. And the new owner of the ship became the clan of Ahzab the Immortal.
About 20 years later, all the clans who wanted to take over the ship united and declared war on Ahzab's tribe. Ahzab's clan managed to escape from this green world by ship, but suffered many casualties.
When they left the black hole with the ship and reached the universe of chaos, there was no trace of those following them. However, the condition of the ship was not very good. They set out for the nearest habitable planet. After many problems the ship quickly entered the atmosphere and it hit the earth and sank into the ground .
Time passed quickly and years later, the immortal Ahzab's clan join a new student.
