Terror

Terror was an almost mythical like superhuman strength weapon capable to the extents of wiping out the entire world. It was dropped on the uronic desert in 2798. After years of radiation, all but a few humans had died out. And Terror was to blame for this. It was later outright banned from being used in Terramus territory, and has since been named Dread of Deadliness.

History
Development of Terror started in 2676 when it was intended to be used on other planets for tests to help our understanding of radiation. Then, The World War broke out... Bayrochon used it against Varichionosto, 2 small state-nations, who are smart and helped make this legendary weapon. The full capabilities of this weapon were not known, and this was the deadly flaw... that's how it came to be banned.
