The System is not ruled by a single empire, but by overlapping spheres of influence. Grineer legions grind across deteriorating planets, Corpus merchant cults harvest profit from the void of space, Infested spores seep through forgotten hulls, and the long-dead Orokin still cast golden shadows over it all.
Against this chaos, Tenno cells operate as precision instruments, tipping local conflicts, shielding civilians and steering the balance away from total collapse. Around the edges, Syndicates and frontier groups like Solaris United and the Ostrons wage quieter wars using politics, memory and leverage instead of fleets.
Use this Codex as both lore archive and tactical brief. Track which factions dominate key regions, what loot and Mods they bring into play, and how their rivalries shape your Missions, Quests and long-term Loadouts.
