- Yariff, Humbal
- Livian historian of the days of the Empire who attempted to deduce the location of Earth from an analysis of known dates of settlement of worlds. This failed partly because the dates were not known accurately enough, partly because of a lack of co-operation from worlds which did not want their mythology questioned and self-esteem destroyed, though in any case it was not known at that time that there were two waves of colonization from Earth. It was not until Janov Pelorat discovered the co-ordinates of the lost Spacer worlds on Melpomenia during Golan Trevize's expedition in search of Earth that they were able successfully to implement Yariff's idea.
