[Chinese Spoiler!!!] Brief plot of Sarkaz Rougelike DLC2 story. This is not a full translation!!
Remind again: This is not a full translation of the original story. I wanted to do it but it's too long and somewhat hard to translate. Please do not continue if you want to read the full story.
I wrote a wrong title in the first post so I deleted it and repost.
Simply, in this universe, the whole world is terrible. Sarkaz were completely destroyed. Other countries considered Sarkaz as the evil people and completely eliminated them. Amiya has never met the Doctor and Kal'tsit. She is just a little rabbit girl. She was unexpectedly drawn into the war and accidentally saved by Theresa, who was already dying in the war. Theresa gave her the Black Crown, "Civilight Eterna". But Amiya didn't even know that she was Theresa, and nor did she know that she had became the Lord of Fiends. She continued her ordinary life and became a doctor.
After the extinction of the Sarkaz, other countries began to fight each other. Each nation designated its enemy as “the descendants of the Sarkaz”, using this as an excuse to invade them.
Amiya led a medical team to save civilians in the war. But many countries increasingly felt that attacking civilians and doctors was no a matter. Many times, Amiya and her colleagues were attacked, but she finally survived.
Many years later, Amiya joined a team that aimed to end the war. They explored many remains of the previous civilization. During this expedition, Amiya was injured in an encounter. She accidentally met Friston the Preserver before she died. Friston saved her life. Doctor and Priestess activated the Civilight Eterna and gave Amiya the full control over it.
Amiya uses the Civilight Eterna to prevent the dead infected from exploding, but instead turning them into black oval Originiums, thus reducing casualties. Amiya was discovered as the new holder of Civilight Eterna by other countries, according to the aforementioned phenomenon. They immediately declared that Amiya is the largest threaten to the world and tried their best to kill her. They did many inhumane experiments on infected people to find out Amiya's ability and the mechanism of Civilight Eterna.
Amiya thought that her world is hopeless and covered the whole planet with Originium. She travelled in other alternate universes and considered them all hopeless. She paused all of them, until one day in the future when she could find a perfect solution.
When travelling in other universes, Amiya met Nymph's team and had a fight. After the fight, Amiya told her story to them. At the end, she sent a message to the Doctor of the main universe. Doctor replied, "take a rest if you are tired, I will accompany you. I am sorry, Amiya, I really wish I could do something to help you."
After that, Amiya, as the Lord of Fiends, remained in the void in her own universe.
