Jan Harrison (born December 18, 1944 in West Palm Beach, Florida) is an American painter and sculptor whose work, which primarily features animal imagery, centers on animal nature as it relates to human existence and the collective psyche.
 Her art is informed by the philosophy of deep ecology, and a monograph detailing her work describes it as “excavat(ing) the arcane kingdom of the human psyche, so long tyrannized by the repressive and oppressive forces of socialization."
 She has exhibited widely in the United States and abroad, and her work is featured in "In The Making: Creative Options for Contemporary Art".
 She currently lives and works in New York’s Hudson Valley.
Paul Chavez (born July 1, 1964) is an American composer of dance music, and a sound designer for installation and theater.
 He often composes under the project name FeltLike.
 Chavez has worked in the Los Angeles, California area since 1990 where he did some of his first works at Los Angeles Contemporary Exhibitions where he started as a sound engineer.
 Chavez's music is influenced by the minimalism of Steve Reich and Paul Dresher and the experimental music of Robert Ashley and Laurie Anderson.
 His work has been featured at the REDCAT Theater in Los Angeles (part of the Walt Disney Concert Hall) and his recent score for the Arcane Collective's dance work Cold Dream Colour was created in collaboration with U2's The Edge.
Bidayuh is the collective name for several indigenous groups found in southern Sarawak, Malaysia and northern West Kalimantan, Indonesia, on the island of Borneo, that are broadly similar in language and culture (see also issues below).
 The name "Bidayuh" means 'inhabitants of land'.
 Originally from the western part of Borneo, the collective name Land Dayak was first used during the period of Rajah James Brooke, the White Rajah of Sarawak.
 At times they were also lesser referred to as Klemantan.
 They constitute one of the main indigenous groups in Sarawak and West Kalimantan and live in towns and villages around Kuching and Samarahan in the Malaysian state of Sarawak, while in the Indonesian province of West Kalimantan they are mainly concentrated in the northern Sanggau Regency.
 In Sarawak, most of Bidayuh population are found within 40 km of the geographical area known as Greater Kuching, within the Kuching and Samarahan division.
 They are the second largest Dayak ethnic group in Sarawak after the Iban and one of the major Dayak tribes in West Kalimantan.

The runecaster or runepriest is a playable character class in the "Dungeons & Dragons" fantasy role-playing game.
 The runecaster appeared in multiple forms in second edition and third edition and as the runepriest in fourth edition, with rune magic also appearing in other editions of the game.
 The runecaster has been implemented as a warrior or fighter class, an arcane or wizard class, and a divine or priest class as well as a set of options for including rune magic without need of a specialized class.
 While rune magic is found in all editions of Dungeons & Dragons, at least as spells, specialized runecasters have not appeared as classes or class-like options in every edition.

 Breeding takes place in streams.
 It is very rare in Mexico and El Salvador but abundant at two Guatemalan sites.

 In the early medieval period, some leading Continental scholars were exponents, including Johannes Scotus Eriugena and Odo of Cluny.
