The Sun's Traveller

In the year 2124, in an alternate universe, General Celineya of the Lumines (generally called Lena) has been hardened by war and fighting the Penumbras for years. After all this time, defeating their leader is almost in sight. She looked forward to years of peace without revolt. At least before their leader sent her back to the past to the year 2020 - much to Lena's dismay.

She resolves to prevent the revolts from happening by getting rid of them even now in the past. Hopefully, by enlisting James, who would grow up to be the immortal leader of the Penumbras and the person to send her in the past in the first place, she can settle the conflicts that would eventually lead to the great war. PLUS, she would have James' trust and perhaps he would not even start the war in the first place. Will she really nip this thing in the bud before it was too late? Or would she make things so much worse than they were before?
