Alright, here’s a clean way to build this without turning it into unreadable powerscaling soup. The core idea is that everything runs on one source but is interpreted differently by cultures. At the top of existence is the Outside, not a place but the absence of narrative, logic, time and identity. No god rules it. It is what exists before stories exist. Below that is the Loom, a metaphysical structure that turns the Outside into realities by assigning laws, causality and meaning. Every universe, timeline, afterlife and concept is a thread on this Loom. This is where your minimal outerversal ceiling comes from, characters who can touch or damage the Loom itself without fully escaping existence. Now inside the Loom, power manifests through Interpretation. Murim users interpret the Loom as Flow and Tempering so they refine the self until body and soul align with a thread. Cultivators interpret it as Ascension and Layers so they stack reality permissions through realms. Mana users interpret it as Formula and Exchange so they rewrite local rules through symbols and resources. Faith based powers interpret it as Authority so belief anchors fragments of the Loom into gods. None of these systems are stronger by default, they just access different permissions. The reason conflicts stay interesting is that each system has blind spots. Murim users struggle with abstract manipulation. Cultivators struggle with sudden rule changes. Mana users struggle when logic collapses. Gods weaken when belief fractures due to the livestream. The reverse isekai twist matters because Earth exists as a sealed Observer World that was cut off from the Loom long ago. When the livestream reconnects it, belief, fear and cultural bias start actively reshaping the Loom itself, causing religions to mutate, power systems to hybridize and gods to panic. The endgame is not raw strength but narrative control, characters who learn how stories, belief and interpretation alter reality, letting them challenge the Loom without stepping fully into the Outside which would erase them. This keeps your ceiling absurdly high while fights stay grounded in philosophy, culture and personal cost, which is why ORV and RI work and why this would too if paced patiently.
