Forum:Is "Rift war" an in-universe term in the story of the same name?

Coming across the Harrowkind page, it mentions a "rift war", pipe-linking to a disambiguation page of a series of comics, which was later made into a graphic novel.

Was this put there by the editor because of the work's name, or is the term in-universe and the page needs disambiguating? -- Tybort (talk page) 17:34, September 16, 2011 (UTC)
