Context paragraphs:
Family Values Tour 2007: The Family Values Tour is a rock tour headlined by Korn.  Korn founded the Family Values tour in 1998 and headlined the first edition.  The next two lineups, in 1999 and 2001, were topped by Limp Bizkit and Stone Temple Pilots, respectively.  In 2006 they revived the tour after a 5-year hiatus.  Several legal disputes ensued over injuries and even a death resulting from fights between concert-goers, but despite the negative connotation, Korn plans to continue the tour onward in 2007, with a whole new set of bands, possibly some old ones as well.

Old Ones (Buffy the Vampire Slayer): In the Buffyverse, the Old Ones are the extremely powerful, pure-breed demons that once dominated Earth before humankind appeared.  Illyria is one of these demons (though its real form was revealed only in an illustration) while it's more than likely that Jasmine and her kind (The Powers That Be) ascended to their higher plane because of the growing malevolence of these warring demons.  It's also possible that the Powers that Be were part of the same race but shared a different philosophy than the other Old Ones.

H. P. Lovecraft Historical Society: The H. P. Lovecraft Historical Society or HPLHS is the organization that hosts Cthulhu Lives! , a group of live-action roleplayers for the "Cthulhu Live" version of "Call of Cthulhu".  Founded in Colorado in 1984, it is now based in Glendale, California.  Their motto is "Ludo Fore Putavimus" ("We thought it would be fun").

Nevinbimbaau: Nevinbimbaau (or Nevinbumbaau) is a goddess in the Melanesian mythology of Malekula Island, Vanuatu.  Some descriptions call her an ogress while others seem to speak of her as simply a female figure.  Her rituals involve a complicated story about her son Mansip, his two wives and their children, Nevinbimbaau's grandchildren.  The ritual begins with actors operating large staffs topped with carved heads, like stick puppets, representing the grandchildren (the "temes nevinbur").  In the course of the ritual, some or all of the temes are destroyed, new ones are created, and at the end wooden effigies of Mansip and his two wives are speared and burned.  The ritual's purpose may have been to initiate new members, and may have something to do with reincarnation or resurrection, since new "temes" are created after the old ones are destroyed (Poignant 1967).

Scaphyglottis: Scaphyglottis is a genus of orchids native to Mexico, Central America, northern South America and parts of the Caribbean.  The current concept of this genus is the result of combining several genera which have been described at various times.  The concept is characterized by the growth habit: not only are new pseudobulbs added at the base of the old ones (as is typical of sympodial orchids), but new pseudobulbs also grow at the apices of the old ones.  Many species are quite similar and difficult to distinguish, but some are clearly distinct.  A few have showy colors.  The genus comprises nearly 70 species.

Unspeakable Vault (of Doom): The Unspeakable Vault (of Doom) or Weird Tales from the Old Ones is a webcomic by François Launet, which chronicles the "daily" lives of the Great Old Ones, including Cthulhu, Nyarlathotep, and Yog-Sothoth, among others.  It takes a lighthearted view of H. P. Lovecraft's Cthulhu Mythos to inspire laughter rather than the more usual soul-blasting horror.  The comic was used as the basis of the second expansion set to the Cthulhu Mythos themed version of Steve Jackson Games' card game "Munchkin".

Elder Thing: The Elder Things (also known as the Old Ones and Elder Ones) are fictional extraterrestrials in the Cthulhu Mythos.  The beings first appeared in H. P. Lovecraft's novella, "At the Mountains of Madness" (published in 1936, but written in 1931), and later appeared, although not named, in the short story "The Dreams in the Witch-House" (1933).  Additional references to the Elder Things appear in Lovecraft's short story "The Shadow Out of Time" (1936).

List of The Power of Five characters: This is a list of all the antagonists and protagonists in "The Power of Five" series by Anthony Horowitz.  The series chronicles the war between the Old Ones and the Five Gatekeepers.  The Five are Matthew Freeman/Jesus, Pedro/Inti, Scott and Jamie Tyler (Flint and Sapling) and Scarlett Adams (Scar, or Lin Mo, the Chinese goddess of the sea).  The Old Ones ruled the world for eighty years at the dawn of humanity, but the Five defeated them, and threw them into Hell, causing the demons to await their return for millennia.  Two gates were built in between Earth and Hell to keep the Old Ones out - these are the focus of the series and consist of Raven's Gate, and the Nazca Desert, which is the second gate.

Old Ones (Palladium Books): The Old Ones (sometimes referred to in Palladium Books publications as the Great Old Ones or the Unnameable Beings) are a fictional race of Alien Intelligences within the megaversal setting of Palladium Books' game module PFRPG.  The Old Ones are the most powerful forces ever to have existed in the various Palladium game settings, and their power dwarfs that of 'ordinary' Alien Intelligences, beings which are in general far more powerful than the gods themselves.

Carol of the Old Ones: "Carol of the Old Ones" is a song originally published in the 1988 HPLHS Solstice Carol Songbook, released by the H. P. Lovecraft Historical Society.  With lyrics written by Andrew Leman, it is sung and performed to the tune of "Carol of the Bells" by Mykola Dmytrovych Leontovych (itself sung to the tune of Shchedryk), with soprano lead vocals and four-part harmony at various points in the song.  The song is performed by The Dagon Tabernacle Choir; the performers' names are Rebecca Marcotte, Digby Dolmen, J.D. Titan, and Walter Forsythe.  It can be found on the album "A Very Scary Solstice".
