Orb is a fantasy oriental setting, with ninja and samurai as well as non-human races and fantastic creatures.
It was originally created by Mark Smith in the mid-1970s for the Dungeons & Dragons game that he ran while attending Brighton College. Its first published use was in the 1984 Fighting Fantasy gamebook Talisman of Death written by Mark Smith and Jamie Thomson. Following this success, they went on to produce the Way of the Tiger gamebooks together, also set in Orb.
In 2013 Megara Entertainment published the Way of the Tiger role-playing game under licence, further expanding the background and scope of the Orb setting.
