It is implied that all First Knights and later Kings of Daventry have been decendents of Legenimor.
Behind the scenesEdit
First Knight is an unofficial term used in the AGDI universe of games. It is not found in any of the official sources.
While the exact details of the tradition are not clear, it seems as long as a king has a blood heir, the prince will also be the First Knight. But if something breaks the lineage, someone else, usually a relative (perhaps distant relative) may be chosen to become First Knight, as was the case with Granthithor, Graham, and Connor. Technically it is not known if Connor actually is a distant relative within the lineage of the First Mages, so it is possible that the tradition has been broken at times.
