The foundational plane of existence, sacred and generally inaccessible. It is the reality which contains the true, indomitable form of the Saegrun Arbor. Its nature is governed by the Law of the Veiled Arbor, meaning it is not to be directly witnessed, only experienced through its projections.
The physical projection of the Saegrun Arbor, manifesting as the mundane cosmos. It is governed by the Law of Hostile Infinity, a near-endless vacuum known as the Outer Wastes. All life and civilization within this plane exists only in the finite, sheltered Glades hidden within its floating spheres.
An ontological echo of the true Saegrun Arbor, a plane where its metaphysical structure is projected as a traversable geography. It is the sole network for inter-Glade travel, a medium governed by Resonant Pressure that creates a natural 'downhill' current toward the Crownwood Confluence. Its living Root Membranes are protected by the Law of Harmonic Integrity; travelers moving too fast create Dissonant Vibrations, compelling the Rootfiends to attack.
