The air in the heavily fortified secret base crackled with tension. A holographic projection of a sprawling, menacing fortress dominated the center of the large table, its imposing silhouette casting a shadow over the assembled heroes.

Steve Rogers, his gaze fixed on the holographic image, addressed the assembled heroes. **"We've enjoyed some victories in this conflict," he acknowledged, his voice grave. "But we knew this wouldn't be easy. And it looks like Stark and S.H.I.E.L.D are working overtime."

A holographic display materialized beside the fortress, showcasing a list of names – Natasha Romanoff, T'Challa, James Rhodes, Vision, Reed Richards, Bruce Banner, Thor, Eddie Brock, and many others – all prominent figures who had signed the controversial Sokovia Accords.

"They've been rounding up unregistered heroes and criminals like there's no tomorrow," Luke Cage interjected, his voice booming across the room. "In fact, we hear they're running out of room to hold 'em all."

Bruce Wayne, his gaze intense, spoke next. "Intelligence obtained by Cable now indicates the pro-registration forces have almost completed construction of a massive new detention facility in the Negative Zone."

He manipulated the hologram, revealing a chilling sight – a vast, fortress-like structure, its cold, metallic exterior gleaming ominously. "It appears that the only way to access this new prison is via a network of tightly guarded portals. Obviously, it sounds like a very secure facility." The room fell silent, the weight of the information hanging heavy in the air. The fate of countless heroes, and perhaps the very fabric of their world, hung in the balance.
