Years after Tony’s sacrifice in Endgame, most Stark tech has been locked away or seized by global governments. But Kael inherited something no one knew about: A hidden subterranean forge known as The Crimson Vault — a cave Tony secretly rebuilt after his original escape in Afghanistan. This new cave is carved into a mountain ridge, reinforced with vibranium-lined stone, and powered by a next-generation arc reactor core buried deep beneath it. Unlike Stark Tower… this place is off-grid. Invisible. Untouchable.
