Overview of Omicron
Omicron is one of the seven planets in the L’estrade Sector and holds the distinction of being the farthest planet into Terminid-controlled space where Super Earth forces have ever spread Democracy. Due to its extreme position at the summit of the Terminid Front, it has always been a high-risk target for Helldiver expeditions. Omicron is also unique in that it possesses an FTL connection outside of the L’estrade Sector but is completely disconnected from the rest of its own system.
Topography
Omicron is known for its lush, perennial forests and vibrant shrublands, making it a hauntingly beautiful world amidst the horrors of war. Its temperate montane climate has been described as reminiscent of the ancient Alps, the Black Forest of Sector 4, and the vast northern woodlands of Sector 7. Despite its natural allure, Omicron has been fully infested by Terminids, who have left its majestic landscapes deceptively untouched in an attempt to lure unsuspecting Helldivers into deadly ambushes.
History
Omicron was never officially designated as a priority target by Super Earth High Command, but its strategic importance and location led to multiple Helldiver-led expeditions into its territory. During March and April 2184, Helldivers made repeated attempts to liberate the planet, reaching up to 80% liberation at one point. However, the failure of the Terminid Control System (TCS) and the Automaton Invasion of Cyberstan left Omicron inaccessible, forcing the Helldivers to withdraw.
The First Expedition, conducted in March 2184, saw a force of three thousand Super Destroyers attempt to liberate Omicron following the capture of Oshaune and Hellmire. The Helldivers, however, faced unprecedented Terminid resistance, suffering severe casualties and ultimately retreating after the fall of Oshaune and Hellmire. Many Helldivers were listed as Missing-In-Action, and several Super Destroyers disappeared while conducting surveys in L’estrade Sector, leading High Command to plan a future return mission.
The Second Expedition, launched in April 2184, saw a larger Helldiver force—four times the original numbers—return to Omicron. The planet was initially less resistant, with skeletal remains of unknown giant Terminid creatures scattered across the landscape, suggesting internal Terminid conflicts. However, before full liberation could be achieved, both Terminids and Automatons launched large-scale assaults across the galaxy, forcing the Helldivers to withdraw. When the expedition resumed a week later, over forty thousand Helldivers deployed onto Omicron, reclaiming most of the planet by April 29th.
Despite this progress, the failure of the TCS system created an uncontrollable wave of Terminid mutations, forcing all SEAF forces to abandon Omicron and focus on containing the threat in the Umlaut Sector. With Super Earth forces withdrawn, the remaining Terminids on Omicron launched a fierce counterattack, overwhelming the Helldivers still on the planet and reversing all progress. While some high-value scientists, civilians, and military assets were successfully evacuated, Omicron ultimately fell back into Terminid control.
Omicron’s fate was sealed in August 2184 with the apparition of the Gloom—a massive intergalactic nebula composed of highly concentrated Terminid spores originating from Enuliale. Over the following months, the Gloom expanded across Terminid-occupied space, eventually engulfing Omicron and cutting off all SEAF surveillance. By September 10th, only one Super Destroyer remained in Omicron’s orbit, its status unknown. On October 3rd, the vessel’s signal went dead, leaving its fate a mystery. The SEAF suspects the ship may be adrift in space, have crashed onto Omicron, or be slowly limping back to Super Earth on autopilot, though it would take many years before it could return.
With Omicron now completely subsumed by the Gloom, its future remains uncertain.
