Arbran Causal Domain

The Arbran Causal Domain is a label for this cosmos’s local domain of cause‑and‑effect—specifically, the node corresponding to Arbre—in metatheoretic diagrams used by Protists and their successors. In expositions of Complex Protism, the familiar two‑box picture is generalized to a directed‑acyclic network; in that framing the Arbran node functions as a point where theorical information can enter from “up‑Wick” sources and, potentially, pass onward.

During ongoing discussions at the Convox, speakers described a fully generalized sketch that no longer distinguishes between theoric worlds and inhabited ones. In that account, arrows can lead away from the Arbran Causal Domain toward other inhabited worlds. One implication voiced openly was that Arbre itself might, for some other worlds, play the role usually ascribed to the Hylaean Theoric World. Others immediately pressed the question of verification, and it was conceded that such conjectures could not be tested unless contact from those other worlds occurred. The point is presented as a live hypothesis within dialog, not as an established result.

As used here, “causal domain” is conceptual rather than geographic: it names how givens and influences are allowed to flow in the diagram. The structure is expressly one‑way and acyclic (no loops), with branching permitted. The Arbran Causal Domain thus serves as a theoretical reference for positioning our world within a wider web of possible cosmi while preserving ambiguity about whether that web describes reality or merely a useful way of speaking.
