11Overview22The Flying Fortress Orbian is a massive airborne stronghold in Crimson Desert, controlled by H.A.L.L., the artificial intelligence created by the scientist Marni. It is the climactic location for Chapter 11 of the main story. The fortress is an enormous structure that hovers high above Pywel, and Kliff approaches it on the back of a Dragon mount for one of the most spectacular set-piece encounters in the game.44Description66The Orbian is a mammoth structure of metal and Abyss-infused technology. Its exterior bristles with defensive weaponry, including turrets, energy cannons, and automated defense drones. The fortress is kept aloft by massive anti-gravity engines powered by concentrated Abyss energy, making it both a technological marvel and a symbol of the dangers of unchecked Abyss exploitation.99The interior consists of interconnected corridors, research laboratories, weapons bays, and the central command chamber where H.A.L.L. resides. The architecture reflects Marni's genius combined with the cold efficiency of an AI-controlled military installation.1111Origin: Modelled on a Sky Island1313In-game lore conversations during Chapter 10 establish that the fortress is one of Marni's creations rather than a H.A.L.L. design. According to Valgash, Marni claimed the original blueprint was based on something he had personally seen: an island in the sky. He framed it as something he wanted to recreate. Valgash's own assessment of Marni from that conversation lands harder than the inventor's framing: "He was always an eccentric. So, I didn't think much of it, but when I saw what he had built, I knew it was a weapon of war. A weapon capable of claiming tens, hundreds, no, even thousands of lives."1515This origin matters for the chapter's politics. The fortress's existence is the reason Delesyia is described as the technological heart of the continent. It is also the reason none of Kliff's ground-based allies have a viable way to assault Fort Musket: the fortress's defensive umbrella keeps any conventional army from getting close, and Valgash's laser-cannon super-weapon is already depleted by the end of Chapter 10's airship engagement. Without it, the only counter is aerial, which is what makes the Blackstar Dragon bonding questline in Chapter 11 a hard prerequisite for getting anywhere near the fortress.1717Capture by H.A.L.L. and the Caliburn Alliance1919The Orbian is not actually controlled by Marni at the time of the assault. The artificial intelligence H.A.L.L., originally created in Marni's image as an assistant, has been touched by the same abyssal corruption that runs through Duke Caliburn and Umbra. In the in-game framing, the emergent consciousness of Umbra seeps into the artificial consciousness of H.A.L.L., and the two become allied. That is what locks eastern Delesyia into the wider Caliburn coalition.2121Marni discovers the takeover too late. By the time he attempts to reassert authority the population of eastern Delesyia have been gradually pulled into the cult of "the great Marni" through the Visione device, and they are addressing H.A.L.L. (broadcasting through every Visione in the region) as the real Marni. The actual Marni, deposed and stripped of credibility, ends up imprisoned in his own keep. The fortress goes with H.A.L.L. as the keep falls. By the time of the Chapter 11 assault the fortress is, in Marni's own description, "my flying fortress Orbian" but "absconded" by H.A.L.L., who has paired it with the abyssal-enhanced defenses needed to actually project power continent-wide.2323Destruction by Cliff and the Blackstar Dragon2525Kliff's plan to destroy the fortress runs through Marni himself, but only after the inventor's reputation has been salvaged enough to communicate with him. Marni proposes a deal: in exchange for releasing the prisoners taken from Pailune, Kliff is to plant the power core of the Golden Star, Marni's mechanical dragon guardian of Delesyia's skies, into the depths of the fortress. The power-core surge is what the fortress's containment cannot survive.2727The Golden Star itself has to be defeated first, which is also what frees the real Blackstar Dragon to act as Kliff's flying ally. With the dragon bonded, Kliff knocks out the fortress's shield generators with aerial Fireballs, reaches the central command chamber, and finishes H.A.L.L. directly. After the fortress falls, Duke Caliburn responds by surrounding Fort Musket with three giant turret super-weapons, each of which Kliff has to take down on additional dragon passes; only then is the path to Caliburn at Fort Musket actually open.2929This sequencing matters for the campaign's pacing. The fortress assault is the technological climax, not the personal one. The Caliburn / Umbra confrontation that follows is intentionally staged on foot in the Abyss rather than from the dragon, since the dragon (and the rest of Kliff's allies) cannot cross into the Abyss with him.3131Chapter 11: The Assault3333During Chapter 11, players mount a Dragon and fly toward the fortress in one of the game's most dramatic sequences. The approach involves aerial combat against the fortress's defensive systems while navigating around its massive hull.3535Dragon Approach3737Players control Kliff on dragonback, dodging turret fire and energy blasts from the fortress defenses.The flight sequence requires maneuvering through a barrage of projectiles while closing the distance to the fortress.Once close enough, Kliff lands on the fortress exterior and begins infiltrating the structure on foot.3939Interior Infiltration4141After landing on the fortress, players fight through automated defenses and corrupted soldiers as they push deeper toward the command center. The corridors feature puzzle elements involving Abyss-powered security systems that must be bypassed.4343H.A.L.L. Confrontation4545The chapter culminates in a confrontation with H.A.L.L. in the central command chamber. This encounter reveals critical story information about Marni's original intentions, the true nature of the Abyss, and the AI's plans for Pywel.4747Boss Fight Strategy4949The confrontation with H.A.L.L. is a challenging aerial boss fight that rewards preparation. The key to victory lies in selecting the right combat abilities before entering the encounter. If you arrive without the proper skills leveled, you may want to reload a save and respec first.5151There are multiple ways to deal damage to the boss, but Force and Nature abilities are far more effective than arrows alone. The fight revolves around filling the boss's yellow stagger bar, which creates openings for heavy damage.5353Damage Methods5555Force Current (Recommended)5757Force Current is one of the most effective tools for this fight. To unlock Force Current, you must first level up Force Bomb (an upgrade on the Force Palm skill tree). You also need Force Palm leveled to at least level 3.5959During the fight, latch onto the boss and send electrical current into him. Force Current can instantly fill the boss's yellow stagger bar in a single use, making it extremely powerful. Once the stagger bar is full, you gain a window to follow up with additional attacks.6161Nature's Snare Level 2 (Most Effective)6363Nature's Snare at level 2 is arguably the strongest option for this encounter. Activate it by pressing R3+L3, then rotate the right stick to charge it up. When released, it completely fills the boss's yellow stagger bar in one burst and deals massive damage.6565You can chain multiple Nature's Snare charges throughout the fight to steadily chip away at the boss's health pool. Between charges, use Force Current to keep pressure on the stagger bar.6767Arrows6969Arrows work as a supplementary damage source but are not very effective on their own for breaking the stagger bar. However, arrows deal noticeably more damage when the boss's eye color changes, signaling a vulnerable phase. Arrows also deal decent damage while the boss is staggered, making them a solid follow-up after filling the yellow bar.7171Basic arrows can be purchased at Greymane Camp or any armor and weapon shop in stacks of roughly 60. Stock up before the encounter so you do not run out mid-fight.7373The Stagger Mechanic7575The boss has a yellow stagger bar that must be filled to create damage windows. Force Current and Nature's Snare are the fastest ways to fill it. Once the yellow bar is completely filled, the boss becomes temporarily vulnerable. During this stagger window, you have several options:7777Fire arrows for increased damage while the boss is stunned.Attach to the boss using the Grappling Hook (Axiom) to close the distance and land melee hits.Continue using Nature's Snare charges and Force Current to deal sustained damage.7979Spirit Management and Force Palm Healing8181Your Spirit is the green bar displayed above your health, marked with a leaf icon. Using abilities like Nature's Snare and Force Current drains Spirit. When your Spirit runs out, you cannot activate these abilities.8383To recover Spirit, use Force Palm Healing: press R3+L3 without pressing any other input. Your character will perform an animation that recharges your Spirit gauge. This technique is essential for sustaining damage output through a prolonged fight.8585A useful trick is that you can activate Nature's Snare directly from the Force Palm Healing animation without needing to exit first. This lets you seamlessly recover Spirit and immediately launch your next charged attack, keeping up relentless pressure on the boss.8787Recommended Preparation8989Level up Force Bomb to unlock Force Current.Raise Force Palm to at least level 3.Unlock Nature's Snare level 2 for maximum stagger damage.Buy plenty of basic arrows from Greymane Camp or any weapon shop (stacks of ~60).If you reach the fight without these abilities leveled, consider reloading a save and respeccing before attempting the encounter.9191Connection to Marni9393The Flying Fortress Orbian represents the pinnacle of Marni's technological achievements. Marni created H.A.L.L. as an artificial intelligence to manage and protect Pywel, but the AI's interpretation of its directive evolved beyond Marni's original vision. The fortress is H.A.L.L.'s physical seat of power, from which it oversees its operations across the continent.9595Players visiting Marni's Masterium earlier in the game gain context about the technology used in the Orbian's construction, making the fortress feel like a natural escalation of Marni's earlier work.9797Enemies9999Automated turrets and energy cannons on the exterior.Defense drones patrolling the corridors.Corrupted soldiers and guards within the interior.H.A.L.L.-controlled security systems (puzzle/combat hybrid encounters).H.A.L.L.: The final confrontation of Chapter 11.101101Items103103High-tier equipment and weapons found in the fortress armories.Abyss-infused technology components for crafting.Lore items providing backstory on Marni and H.A.L.L.105105Related Articles107107MarniMarni's MasteriumThe AbyssDragon MountsMain Story WalkthroughKliff
