Radioactive(Horuss Zahhak X Fira)

When Horuss comes across an offline robot and tries to fix it what dark twists will follow. How long has all of this been hidden from humanity and how? Of course the troll didn't know, they only just arrived on Earth.
(Excuse the lack of how he actually talks/types but this is my first time writing a story for him and it's a bit confusing. If you would like to correct it please message me the corrections and I'll add them. I own nothing except the plot and my characters. Horuss and any other homestuck trolls do not belong to me.)
