In 2087, you had just started working at "The Tower." At the end of the year, you accompanied your mentor to the "Global AI Application Sentinel Summit." At the summit, you met many high-ranking officials from "The Tower," and you realized this would be a meeting of extraordinary significance for all humanity. However, towards the end of the conference, the Dark Faction attacked the venue. This was your first direct encounter with the "Sentinels" of the Dark Faction—they were formidable, highly intelligent, and tyrannical, like invincible gods descended from the heavens. Fear swept over everyone... and then you met Arix.
