Deathstrike

Deathstrikes are events of mass destruction inflicted by a person who is in macroshock. Historically, deathstrikes are used to annihilate all life on a planet, and scar the person who cast it with a morose reminder of their atrocity. The most famous instance is the deathstrike of Bulvaron, which ended the Human Expansion Era massively changing galactic history onward.
