Both are served from our own server. We do not load fonts from another company’s servers.

• GeoNames geographical database (cities of 1,000 people or more), used for birthplace and place search, under the Creative Commons Attribution 4.0 licence. We loaded a copy onto our own server and do not change its meaning.
• Crystal Encyclopedia photos are from Wikimedia Commons. Each photo is credited under it with its photographer and licence (mostly Creative Commons Attribution or Attribution-ShareAlike; some are in the public domain), with a link to its page on Commons. We made smaller copies and changed nothing else. Where Commons has no photo of the exact stone, a similar stone is shown and the caption says so.
• Claude, a model from Anthropic, PBC, writes up readings from the facts and descriptions we give it (see the Disclaimer).
• Stripe handles payments, Cloudflare Turnstile checks that sign-ups are made by people, and Cal.com books One-On-One sessions. The names and marks are theirs.

• Hávamál: the stanzas are from Olive Bray’s 1908 translation of the Elder Edda, which is in the public domain. We used the text on D. L. Ashliman’s online edition and compared it with a scan of the book.
• Völuspá, Grímnismál and other Eddic poems; Gylfaginning: quotations are from Benjamin Thorpe’s Elder Edda translation and from the Younger Edda as translated in the Norroena Society edition (London, 1906), both in the public domain.
• Background text: some background and context in the Lorebook is summarized from articles on English Wikipedia, whose text is available under the Creative Commons Attribution-ShareAlike 4.0 licence; the articles’ page histories list their authors. Such text is a secondary summary, not a scholarly source.
• Everything else in the Lorebook, including the paraphrases and the modern readings, was written for this Site. Where it says so, a reference marked “verified” has been checked against the source named.

• The Yggdrasil map in the Lorebook is an illustration made with an AI image tool. It is interpretive and is not a historical map.
• If you own artwork, a photograph, an animation, a sound or other material that you believe appears on the Site without your permission, or that needs a credit we have not given, email [email protected] with a link and we will look at it promptly (see also “Copyright complaints” in the Terms of Service).
