Garret is a cyborg that crash lands on the Sentinelese Islands in the Bay of Bengal after being shot down in a war that pits an entity claiming to be the One True God versus what people are saying is a new God, created by humanity to fight the fake one, who simply calls himself "The Newcomer."
The cyborg is badly damaged, and can barely move from where his crashed aircraft spit him out on the shore. Now he has to handle repairs, all while getting shot at, and all in the middle of a massive battle over his head, that he's just been ceremoniously kicked out of. But the battle could come to the island at any moment.
If he doesn't find a way to return to it soon, the war to let the Real God Please Stand Up could be lost.
The New God is still just a babe in the crib, and he needs Garret's help.
(Note-The Senintelese Islands and People are real. Their hostility is not really exaggerated. Look them up!)
