Álfheimr — the one true spelling, and the forms that fail it
A letter to a colleague, 31 July 2026 — on the name Álfheimr, and on the forms that keep failing it.
Your note said, roughly: surely the marks are a nicety. Permit me to use Álfheimr to show they are not.
First, the attestation. The attested form is ᛅᛚᚠᚼᛁᛘᚱ, from the tradition's own record. The canonical transliteration is Álfheimr.
And the marks themselves: a → Á (Acute on initial alpha). Remove any one of them and you have not simplified the name — you have told a small lie about it, and small lies in references have long consequences.
Say it aloud as the sources heard it: 'AHLV-haymr' — stress the first syllable like 'owl' without the w, then a quick 'lv-haymer' with a rolled final r. The marks are what carry that sound to a reader who has never heard it spoken.
On the plain form — and I want to be precise, because you pushed on this. The plain form alfheimr is not false — it is a fallback, and the register is exact about what that means. In systems that cannot carry diacritics (legacy databases, older tooling, parts of the address-bar pipeline) the flattened form is the accepted vehicle, and the rulebook names it explicitly as the final rung of the fallback hierarchy: full restoration first, circumflex where attested, macron-only by the academic standard, an attested variant, and only then plain ASCII.
What the fallback status forbids is promotion: alfheimr may carry the name where marks are impossible, but it may not represent the name where marks are possible. Every mark it drops — a → Á — is a fact the sources recorded. A fallback is a vehicle, never the primary.
One more thing, because it always surprises: the name did not stay home. Álfheimr's afterlife is a study in survival through renaming. As Christianity took hold, the álfar were never formally condemned — they slipped sideways into the folklore of the landvættir and, in Iceland, the huldufólk, the 'hidden people', whose dwellings were respected into the modern age; later saga tradition muddled Snorri's dark elves with dwarfs until the categories nearly merged.
And it never stopped working. Álfheimr today lives a double life. In Iceland, belief-adjacent respect for the huldufólk remains culturally legible — road projects have been rerouted around suspected elf-rocks, and the hidden people still surface in polls and news copy as a way of talking about the land's claims.
The Convention's Own History
The Poetic Edda survives essentially in one manuscript — the Codex Regius, c. 1270 — and normalized Old Norse spelling descends from what that manuscript and its siblings actually write. Þ and ð are not decorations: they are letters of the alphabet the skalds used (and English later abandoned), and ǫ is a nasal vowel the normalization preserves because the sources carry it. The register's rule is the manuscript's rule: spell the names the way the tradition that sang them wrote them down.
Where Protocol Meets Practice
The technical answer is simple: the canonical marks are legal IDNA 2008 characters, encoded as punycode under `xn--`. The practical answer is messier: legal does not mean stocked (registrar inventory is partial), and stocked does not mean typeable (stacked diacritics defeat mobile keyboards).
So the register's rule is a hierarchy of attested forms — full restoration, circumflex, macron-only, attested variant, and finally plain ASCII for the systems that cannot carry marks. Every rung is defensible because every rung is attested. The forms this register rules against are not rungs; they are errors, and errors do not get rungs.
Write back when you have checked the sources; they are better company than I am.

The Verdict
Álfheimr is the canonical form: attested, checkable, and enforced across the temple, the lexicon, the cards, the APIs, and this register. The plain form alfheimr is sanctioned as the fallback vehicle and nothing more. The false forms above are documented so that no reader has to take the temple's word on faith — the violations are stated, the sources are named, and the register stands open to challenge on every line.
The temple of Álfheimr stands at /alfheimr/.
The docket for this ruling: no false forms on the docket; 1 preserved mark verified: a → Á; no contested forms attested; the attestation rests on 5 cited sources — Poetic Edda: Grímnismál 5 (Álfheim given to Freyr as tannfé); Alvíssmál 9–35 (the elves' names for the world); trans. Carolyne Larrington (Oxford, 2014)., Snorri Sturluson, Edda: Gylfaginning ch. 8 (the light and dark elves of Álfheim), trans. Anthony Faulkes (Everyman, 1987)., Sigvatr Þórðarson, Austrfarvísur sts. 4–6 (the álfablót), in Diana Whaley (ed.), Poetry from the Kings' Sagas 1 (Skaldic Poetry of the Scandinavian Middle Ages I, 2012)..
The Register Continues
Entry 19 of 546 in the Canonical Register. Around it: the temple's founding dispatch, the Restoration File on the marks themselves, the Resonance File on the archetype at work, and the Rulebook behind all of it.

The Canonical Register is written from the same canonical record as the lexicon itself. If a false form is missing from this page, it is because the evidence does not support calling it false — or because we have not seen it yet. Show us, with a citation, and the register will answer.
