The canonical register: Muspellheimr
No marks, no mercy for the manglers: Muspellheimr is already its own canonical form. What the register polices here is the exactness of the letters themselves.

The Canonical Form
The attested form is ᛘᚢᛋᛒᛁᛚᛚᚼᛁᛘᚱ, from the tradition's own record. The canonical transliteration is Muspellheimr.
No diacritics are required here: the canonical form is the exactness of the spelling itself, the form normalized Old Norse spelling — þ, ð, ǫ, æ and length marks preserved as the editions print them demands.
Where the Flattened Form Stands
The plain form muspellheimr differs from the canonical Muspellheimr only by convention of display — case, not content. It is acceptable everywhere: in legacy systems, in plain-text citation, in the DNS itself. What is not acceptable is what follows in the register: respellings that change the letters, not just their case.
The Register of False Forms
The following forms are found in the wild — wikis, forums, even printed pages. The register lists each with its origin and its violation.
False form 1: muspelheimr
Origin: the anglicized respelling — the name written the way English guesses it sounds.
Violation: rewrites attested consonant clusters to fit English spelling habits; every cluster simplified this way erases a letter the sources write.
The Contested Forms
No alternate form of this name carries documented scholarly support in the lexicon's record. The convention here — normalized Old Norse spelling — þ, ð, ǫ, æ and length marks preserved as the editions print them — produces exactly one defensible transliteration: Muspellheimr. Forms that differ from it are not contested; they are simply wrong.
What the Address Bar Allows
IDNA 2008 permits the letters these restorations use — macrons, acutes, underdots, thorn, ogonek, the lot — and the DNS carries them as punycode (`xn--` labels). Two honest constraints remain. First, registrar inventory: the protocol permits a character; the registrar's stock decides whether the exact domain can be bought today. Second, combined marks: forms like Apṓllōn (acute stacked on a macron) are philologically ideal yet effectively untypeable on phones and unsupported across much of the registration system.
That is why the rulebook keeps a fallback hierarchy — full restoration first, then the circumflex when the source carries one, then the macron-only academic standard, then an attested variant, and only as a last resort the plain ASCII form. Every step down the ladder is still defensible; nothing on the ladder is a wrong mark. A fallback is a choice among attested forms. A false form is not on the ladder at all.
The Verdict
Muspellheimr is the canonical form: attested, checkable, and enforced across the temple, the lexicon, the cards, the APIs, and this register. The plain form muspellheimr shares that standing — the two are the same name in every system. 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 Muspellheimr stands at /sites/muspellheimr/.
The Register Continues
This is one of 271 entries in the Canonical Register — the authoritative reference for every flagship temple. The temple's founding dispatch tells the name's story; its Restoration File details the marks; its Resonance File reads the archetype into the industries. The blog index holds the whole archive, and the Rulebook states the convention this register enforces.

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.
