Title: **Sands of Sigma-7** *Background:* In the far reaches of space lies Sigma-7, a desert planet orbiting a lone star at the edge of Union space. Once a thriving colony, Sigma-7 fell into decay after its main resource, a rare mineral known as Helioxite, was depleted. What remains now are the husks of old mining operations, small frontier towns struggling to survive, and the ever-present, roving bands of scavengers and outlaws. Recently, however, whispers have surfaced of a new vein of Helioxite, attracting interest from all corners of the galaxy. **ACT 1: The Shattered Oasis** *Session 1: Winds of Arrival* The player characters (PCs), a squad of rookie LANCER pilots hired by the reputable but secretive corporation known as Prodigium, arrive at the desert planet Sigma-7. Their mission is to secure the newly discovered Helioxite vein for Prodigium, ensuring that it doesn't fall into the hands of the various dangerous factions on the planet. *Session 2: Sandstorm Serenade* While en route to the Prodigium basecamp, a massive sandstorm forces the PCs to seek shelter in a dilapidated settlement named Dust Haven. During their stay, they must defend the town from a raid by Marauders, gaining the trust of the locals and learning more about the planet's challenges. *Session 3: Echoes of the Past* The PCs discover a stranded group of archaeologists who have unearthed an ancient facility powered by previously unknown technology. The squad protects the archaeologists while they extract valuable data, but they must fend off another faction which seeks to claim the facility's secrets. **ACT 2: Helioxite Heartbeat** *Session 4: Desert Sentinels* Prodigium's basecamp is threatened by an enormous creature disturbed from its slumber by mining operations. The PCs must pilot their LANCERs in a battle against the creature while simultaneously protecting the base from collateral damage. *Session 5: The Vein's Whisper* The PCs are tasked with escorting a convoy carrying mining equipment to the Helioxite vein's location. During the escort, they encounter environmental hazards and must outmaneuver a rival corporation's mercenaries attempting to hijack the convoy. *Session 6: Ghosts in the Machine* Upon arrival at the Helioxite vein, the PCs must help set up defenses and operational facilities. While doing so, they uncover an ancient, automated defense system that activates and perceives them as threats. The pilots must disable the system without destroying it, revealing a deeper mystery on Sigma-7. **ACT 3: A Breath of Dust** *Session 7: Crimson Dune Showdown* A coalition of bandit factions, united by a charismatic warlord, launches a full-scale assault on the mining operation. The PCs are in the thick of it, utilizing their mechs and wits to fend off the attackers and protect the valuable Helioxite. *Session 8: The Sigma Standoff* Tensions come to a head as a three-way battle ensues among Prodigium, the coalition of Marauders, and a surprise third party: a Union Peacekeeping force aiming to stabilize the region. The PCs find themselves caught between their obligations and the greater good. *Session 9: Helioxite Heart* In the campaign's climax, the PCs explore an underground complex beneath the mining site, which turns out to be an ancient alien facility. The Helioxite apparently is a byproduct of the facility's power source. As they attempt to harness its power, they awaken a dormant AI that has been protecting Sigma-7. The PCs must choose whether to ally with the AI to protect Sigma-7's secrets or secure the Helioxite for Prodigium, which may have its own hidden agenda. **Epilogue:** The fate of Sigma-7 and the precious Helioxite vein are in the hands of the PCs. Their decisions throughout the campaign lead to a multitude of possible endings: Do they become wealthy heroes of Prodigium, defenders and protectors of Sigma-7 tasked by the alien AI with new responsibilities, or catalysts for change by aligning with the Union to bring long-term peace and stability to the region? This campaign is set up to allow beginner LANCER players to gain familiarity with various gameplay aspects: piloting their mechs in combat, making strategic decisions, and interacting with the world on a political and ethical level.
