I met it on a Tuesday. The rain had been scraping the windows clean all morning, wiping the fingerprints off the skyline until the glass looked like black water. My apartment smelled faintly of solder and stale coffee; my workstation blinked with an ocean of open ports. The file came wrapped like a dare: Ares_Mod_Free_Craft.exe. No signature, no author, only a timestamp and a checksum that didn't match anything in the registry. I should have deleted it. I did not.
