Proxy bidder Tok on Domo took the opening bid for Avon from Valeria of Prim. Whoever she was, she dropped out at a fairly early stage. Prim may have been a planet, or a location on an unnamed planet.
| Name applied to descendants of the settlers on Chenga who had chosen to live a simple, technologically unsophisticated life. They were hunted for sport or bounty by the Hitechs who used them as a source of organs for transplant surgery. Vila met two Primitives on Chenga, Lom and Mall. | |
| Krantor dressed in a costume which he claimed was modelled on the Prince Regent, one of very few actual historical personages to be named in the series. When George III was declared insane in 1811, his son ruled Britain as Regent until assuming the throne as George IV in 1820. |  |
Abbreviation of the Latin phrase _pro tempore_, which means 'temporary' when used as an adjective. Samor used it in that context when he described himself as having been appointed 'pro tem military arbiter'.
Used by Avon whilst in orbit around Virn because electrical interference had forced him to have Orac switched off. It was a method of analysing a problem by shuffling tokens representing elements of the problem until they took on an order which pointed to a solution. Avon claimed to have got 'very interesting results' from using it and deduced that the sand was feeding off human energy and that it required a breeding pair of humans.
Tool requested by Avon whilst repairing the flight deck of the Ortega. Almost certainly a generic term for a wide variety of instruments.
World from which the menial Relf on Ultraworld came from. Tarrant was told this by the recording in Relf's memory tube.
| Aliens or modified humans carried in cryogenic suspension aboard a sublight vessel carrying gene stocks and brood units from an unspecified place of origin to an equally unspecified destination. The ship was brought aboard Liberator on approaching Cygnus Alpha and the surviving crew (one of the four was long dead) thawed out. |  |
 | They were programmed to protect their cargo from any possible threat, which included Blake's crew, and they injured Jenna, overpowered Gan and drained energy from the Liberator. Jenna killed two of the three remaining guardians (the first people seen to be killed with a Liberator handgun), the third died when he was pushed against a live power cable by Blake and electrocuted. |
Area of space Zen stated as having an "unacceptable risk designation". The terminology suggests that there were several - if not many - such zones, officially recognised and classified. The one crossed by the Liberator on its way to XK-72 contained a massive gravitational vortex.
Travis' plan to plant an android replica of Avalon aboard the Liberator and release a deadly virus modified from the so-called Phobon Plague, enabling the ship to be captured intact. Travis referred to the plan by this title and Avalon was not amused.
A broadcast announcement of "project A6 security green now in operation" may be a reference to Project Avalon or to some other operation.
