Macro-cosmic biospheres

The hyper-scaled, fully functional, and naturally occurring planetary or dimensional ecosystems that house entire divine civilizations within the Abzuverse. In internet worldbuilding subcultures, this term is the ultimate antidote to the lazy fantasy trope of "Heaven" or "Asgard" being just an empty palace floating in a magical void. Instead, a macro-cosmic biosphere is treated as a real, material continent of reality, complete with its own unique atmosphere, weather systems, native flora, and supernatural wildlife.
From the luminous celestial capitals of the Anunnaki to the vast, subterranean rivers of the Egyptian Duat, these environments are governed by cosmological materialism. They aren't held together by arbitrary magic spells, but by a complex, self-sustaining ecology operating at an immense cosmic scale. If a mortal travels to one of these biospheres, they aren't entering an abstract spiritual state; they are stepping onto a physical substrate with real geography, resource scarcity, and environmental cycles that have been running for billions of years. It’s how the Abzuverse anchors ancient mythologies into hard speculative science fiction.

Macro-cosmic biospheres "The crazy part about the Abzuverse is that Olympus isn't just a mountain with twelve thrones; it's a massive macro-cosmic biosphere with an entire localized ecosystem and weather pattern."
"Yeah, it makes the divine worlds feel completely real, like you're exploring an advanced alien planet instead of a myth."
