The tiger (Panthera tigris) is the largest cat species, reaching a total body length of up to 3.3 metres (11 ft) and weighing up to 306 kg (670 lb). They are the third largest land carnivore (behind only the Polar bear and the Brown bear). Their most recognizable feature is a pattern of dark vertical stripes on reddish-orange fur with lighter underparts. They have exceptionally stout teeth, and their canines are the longest among living felids with a crown height of as much as 74.5 mm (2.93 in) or even 90 mm (3.5 in). In zoos, tigers have lived for 20 to 26 years, which also seems to be their longevity in the wild. They are territorial and generally solitary but social animals, often requiring large contiguous areas of habitat that support their prey requirements. This, coupled with the fact that they are indigenous to some of the more densely populated places on Earth, has caused significant conflicts with humans.

Tigers once ranged widely across Asia, from Turkey in the west to the eastern coast of Russia. Over the past 100 years, they have lost 93% of their historic range, and have been extirpated from southwest and central Asia, from the islands of Java and Bali, and from large areas of Southeast and Eastern Asia. Today, they range from the Siberian taiga to open grasslands and tropical mangrove swamps. The remaining six tiger subspecies have been classified as endangered by IUCN. The global population in the wild is estimated to number between 3,062 to 3,948 individuals, with most remaining populations occurring in small pockets that are isolated from each other. Major reasons for population decline include habitat destruction, habitat fragmentation and poaching. The extent of area occupied by tigers is estimated at less than 1,184,911 km² (457,497 sq mi), a 41% decline from the area estimated in the mid-1990s.

Steve Winter is a game designer who has worked on numerous products for the Dungeons & Dragons fantasy role-playing game from TSR and later Wizards of the Coast.

Steve Winter was born in Dubuque, Iowa on December 8, 1957. Winter attended Catholic school for grade school and high school, and had two years of Catholic college before he transferred to Iowa State University at Ames. “A nun introduced me to the works of J. R. R. Tolkien in high school ... Previously, I had been mostly into historical novels and military history. For the next several years, I read all the fantasy I could get my hands on — but I didn’t enjoy very much of it. I couldn’t find anything with the same sense of humor and style as Tolkien. I also read a lot of science fiction.” In 1978, while attending college, Winter worked part time at a department store which carried a few wargames in its small games department. He began playing with the wargame The Russian Campaign by Avalon Hill; “The Russian Campaign intrigued me, so I bought Tobruk, which was the game that changed my life. I played it to death.”

Alan Robert Rabinowitz (b. December 31, 1953) is an American zoologist, conservationist, and field biologist and the CEO of Panthera, a nonprofit conservation organization devoted to protecting the world's 37 wild cat species. Called the "Indiana Jones of Wildlife Protection" by Time, Rabinowitz has studied jaguars, clouded leopards, Asiatic leopards, tigers, Sumatran rhinos, bears, leopard cats, raccoons, and civets. Today, Rabinowitz’s work focuses on conserving the world’s largest, most imperiled cats—tigers, lions, jaguars, and snow leopards—and their habitats.

Rabinowitz grew up in Brooklyn, New York. In grade school, he was placed in a special education class due to a severe stutter; which often caused his body to twist and spasm when attempting to speak. Unable to communicate with his peers and teachers, Rabinowitz became interested in wildlife, to which he could speak. At this point, Rabinowitz made a promise to animals that if he ever found his voice, he would use it to speak in their defense.

Sir David Frederick Attenborough ( /ˈætənbərə/) OM, CH, CVO, CBE, FRS, FZS, FSA (born 8 May 1926) is a British broadcaster and naturalist.

His career as the face and voice of natural history programmes has endured for more than 50 years. He is best known for writing and presenting the nine Life series, in conjunction with the BBC Natural History Unit, which collectively form a comprehensive survey of all life on the planet. He is also a former senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s.

Attenborough is widely considered a national treasure in Britain, although he himself does not care for the term. He is a younger brother of director, producer and actor Richard Attenborough.

Attenborough was born in Isleworth, west London, but grew up in College House on the campus of the University College, Leicester, where his father, Frederick, was principal. He is the middle of three sons (his elder brother, Richard, became an actor and his younger brother, John, an executive at Italian car manufacturer Alfa Romeo). During World War II his parents also adopted two Jewish refugee girls from Europe.
