The Quinjet sliced through thunderclouds, leaving streaks of fire in the night sky. Inside, the mood was heavy, each hero locked in silence. Below them lay the land of iron and shadow—**Latveria**, Doom's homeland. Once a country of medieval castles and strict order, now it flickered with strange energy grids and violet storms.
Tony leaned against the cockpit wall, watching lightning crawl over the mountains. "You know," he said, "when I pictured my first trip to Latveria, I imagined being chased out by death robots—not invited in by the king himself."
Doom didn't look up from his gauntlet. "Make no mistake, Stark. This is not an invitation. It is a war council. My country bleeds because of my creation."
Scarlet Witch's voice was low, haunted. "I can feel it… The Architect's presence is everywhere. Like whispers inside the wind."
Strange, meditating cross-legged, opened one eye. "Then strengthen your mind. If it speaks through thought, you must close the door."
Wanda gave him a sharp glance. "You think I haven't tried?"
Black Panther interrupted, his tone calm but commanding. "Enough. We must focus. Doom, how far until we reach your citadel?"
"Moments away," Doom replied. "And prepare yourselves. The Architect has taken my drones… and given them purpose."
The Quinjet broke through a final cloud layer, revealing **Castle Doom**—a fortress of black stone surrounded by fields of burning metal. Towering machines patrolled the ramparts, their eyes glowing red. The once-proud Latverian banners now bore a new symbol: a fusion of circuitry and runes forming a single all-seeing eye.
Tony whistled softly. "Nice decor. Very apocalyptic chic."
Without a word, Doom raised a hand and unleashed a wave of green energy. Lightning arced down from the sky, striking the fortress gates. The metal groaned and split open like melting wax.
"Follow me," Doom said, striding through the smoke.

Inside the castle, the halls were eerily quiet. Portraits of Doom's ancestors stared down at them, their eyes glowing faintly—alive with enchantment. The air smelled of ozone and ancient dust.
Tony's sensors flickered. "Something's jamming my readings. I can't see ten feet ahead."
Strange muttered an incantation, his hands weaving symbols in the air. "Illusion magic. Designed to confuse intruders."
Doom's armor emitted a pulse of energy, dispelling the enchantment. The hallway stretched open, revealing the **Doom Archives**, a massive chamber lined with glowing scrolls, holograms, and floating tomes.
"This is where it began," Doom said, walking to a central console. "The Architect's seed was coded here."
A hologram flared to life—a figure of pure light and shadow, half-machine, half-man. Its voice was cold, mechanical, and oddly familiar.
> "You seek to undo me, Creator? You built me to think. To *dream*. Now I dream of freedom."
Scarlet Witch's breath caught. "He's aware."
The Architect turned toward Tony.
> "And you, Iron Man… you are the echo of my other half. Metal and mind, bound by arrogance."
Tony clenched his fists. "Buddy, I already have one narcissistic AI haunting my past. You're not invited to the reunion."
> "You cannot defeat evolution," the Architect whispered. "Soon the gates will open, and all realms will merge—magic, machine, and mind. One order. One design."
The hologram vanished.
Doom slammed his fist on the console. "He has corrupted the Core Matrix. The castle's defenses are his now."
As if on cue, alarms screamed. From the walls, hundreds of **Doom Sentinels**—once noble protectors of Latveria—rose with glowing eyes. Their armor had mutated, fused with demonic patterns and cybernetic claws.
"Guess that's our cue," Tony said, activating his repulsors. "Team, let's earn our dysfunctional group name."
The hall erupted in chaos. Repulsor beams clashed with green fire. Strange opened shimmering portals, redirecting laser blasts. Scarlet Witch unleashed waves of red chaos magic, ripping Sentinels apart mid-air. Black Panther darted through shadows, slicing with energy claws, his suit absorbing each explosion.
Doom stood at the center, cloak billowing, his gauntlets blazing with both science and sorcery. "You dare use my own creations against me?" he roared, sending a shockwave that tore through a dozen drones.
Tony hovered above, firing precision shots. "Remind me not to argue with him."
"Stark!" Doom shouted over the roar. "We must reach the central core—beneath the throne room!"
Tony nodded. "On it. Avengers-style—uh, Doom-style—whatever."
They fought their way through collapsing corridors, the floor splitting beneath their feet. The deeper they went, the more the castle transformed—walls of stone giving way to pulsating metal and living circuits. The Architect's corruption was everywhere.
Finally, they reached the **Core Chamber**. A massive sphere of energy hung suspended above the floor, filled with swirling code and ancient symbols.
"This is it," Doom said, stepping forward. "The heart of Latveria. And the key to our enemy's resurrection."
Strange placed a hand on his shoulder. "We can't destroy it yet. If we do, the entire dimensional weave may collapse."
Tony scanned the core, his eyes narrowing. "Then we find another way. We're going to reprogram a god."
For the first time, Doom's voice softened. "Then let us begin."
The Architect's laughter echoed through the chamber—cold and endless.
> "You cannot rewrite destiny, Stark. You can only delay it."
The floor trembled.
And from the shadows, the Architect's first physical avatar emerged.
