Wardhearts and Nexuses
Scope
This file owns the cross-game cosmology of Wardhearts and Nexuses: what they are at the metaphysical level, how they relate to leyline networks and the divine layer, what scales they exist at (Crown-Wardheart and lesser Wardheart), what an Ancient Shield is in cosmological terms, and how Wardhearts interact with the Afterwar and the Crownrot pattern. Specific Game 1 Wardheart instances — including the specific Crown-Wardheart that anchors Game 1's starting Zone, the specific failing Ancient Shield of Game 1, and the specific ruler-defender who holds it — are gl-* scope. The type definitions live here.
Facts
Fact: A Wardheart is a cosmological anchor.
A Wardheart is a point at which leyline energy is concentrated and can be stabilized to repel demon-origin corruption from a surrounding territory. Wardhearts are not buildings or structures; they are the cosmological anchor at a place. Buildings, stones, and ritual sites at a Wardheart are the mortal-world manifestation of that anchor — the Nexus — but the Wardheart itself is the underlying property of the place, not the masonry on top of it.
Canonicity: hard canon

Fact: A Nexus is the mortal-world manifestation of a Wardheart site.
A Nexus is the physical site at a Wardheart: the ruins, stones, structures, sacred grounds, or shrines built up at the anchor point over time. Mortals interact with Wardhearts through their Nexus. A damaged or buried Nexus does not necessarily destroy the underlying Wardheart, but it does impair access to it. A Nexus is the surface; the Wardheart is the depth.
Canonicity: hard canon
Cross-refs: ul-cosmology.md
Fact: Wardhearts exist at multiple scales.
A Crown-Wardheart anchors a region at crown scale — large enough to support an Ancient Shield and to underpin a polity capable of resisting a Demon Cycle peak. A lesser Wardheart anchors a zone or province at smaller scale. Crown-Wardheart and lesser Wardheart are the two committed scales; the full typology of Wardheart ranks is not yet exhaustively committed.
Canonicity: hard canon (the two scales named here); soft canon (the full typology)
Fact: Crown-Wardheart is both a type and an instance distinction.
"Crown-Wardheart" names a TYPE in this file: a Wardheart that anchors a crown-scale Zone, sustains an Ancient Shield, and underpins a polity at the largest scale. The TYPE is universe scope. Each game's specific Crown-Wardheart — which specific anchor, in which specific Zone, sustaining which specific Ancient Shield, defended by which specific ruler-defender — is an INSTANCE and is gl-* scope. Authoring of universe-scope content uses "Crown-Wardheart" only as the type designator; references to the specific Crown-Wardheart of a particular game's Zone live in that game's gl-* files.
Canonicity: hard canon (the type-vs-instance split)
Cross-refs: ul-demon-king-remains.md, ul-divine-layer.md
Fact: Wardhearts were constructed or sealed into place by gods, vessels, or mortal builders.
The origin of any individual Wardheart varies: some were sealed into place by gods directly, some by vessels or marked heroes acting under the Accord of Intervention, some by mortal builders using world-law-correct methods. The variation is by site. There is no single creator class for all Wardhearts; the cosmological role is unified, but the historical origin is not.
Canonicity: soft canon

Fact: A damaged or dormant Wardheart still suppresses demon pressure weakly.
Even a damaged or dormant Wardheart provides some local suppression of demon-origin corruption. The suppression is weaker than that of an active, stable Wardheart, but it is not zero. A dormant Nexus is therefore a place where mortal survival is more viable than the surrounding tainted territory, even before any restoration work is performed.
Canonicity: hard canon
Fact: An active, stable Wardheart creates a Shielded Zone.
An active, stable Wardheart establishes a Shielded Zone around itself: an area where mortal survival is viable despite Afterwar wound conditions in the broader continent. The Shielded Zone is the territorial consequence of a Wardheart's anchor effect, not a separate cosmological feature.
Canonicity: hard canon
Cross-refs: ul-demon-king-remains.md, ul-cosmology.md
Fact: An Ancient Shield is the sustained ward-field anchored by a Crown-Wardheart.
The Ancient Shield is the sustained, large-scale ward-field that a Crown-Wardheart projects across the territory of its Shielded Zone. It is not a separate artifact; it is the Wardheart's anchor effect at crown scale, named for its role and its endurance. An Ancient Shield can fail — partially or fully — if the Crown-Wardheart is damaged, if the leyline feeding it is cut, or if the Wardheart is corrupted by Crownrot or by binding to a heart-fragment.
Canonicity: hard canon
Cross-refs: ul-demon-king-remains.md, ul-cosmology.md
Fact: The Crown-Wardheart anchors a defender office, but the public title labels remain unsettled.
The mortal political consequence of a Crown-Wardheart is that some mortal — by inheritance, by Calling, or by claim — holds the public duty of defending the Zone. That office pattern is soft-canon universe scope. Working honorifics such as Shield-King, Bastion King, and Warden King are attested labels for the office, but the labels remain proposed rather than settled canon and may vary by era or region. The Crown-Wardheart is the anchor; the defender office sits on top of the anchor. A Crown-Wardheart can become Crownrotted; an office-holder can become a false-king. Both are documented in ul-demon-king-remains.md.
Canonicity: soft canon (office pattern); proposed (public labels)
Cross-refs: ul-demon-king-remains.md, ul-divine-layer.md
Fact: Whether Wardhearts can be created by mortals without god assistance is proposed.
Whether mortals, working alone with world-law-correct methods and without divine participation, can create a new Wardheart at a previously-unanchored site is left as a deferred question. Authoring of game content must not assume mortal-only Wardheart creation until this is resolved.
Canonicity: proposed
Fact: The maximum number of Wardhearts a single divine patron can sustain is bible-only.
Whether there is an upper bound on how many Wardhearts a single god can sustain across the divine layer is reserved as bible-only material. It is not surfaced in any player-facing content.
Canonicity: bible-only
