Arms and Armor Theme Naming

Authors like to use themes to create a sense of unity or cohesiveness within their work. Some extend themes to the names of the characters, often beyond the similarities that would be expected for characters from the same culture or who all speak the same language. One variation is to name a set of characters or groups after weapons or armor. This almost invariably has martial meanings. Characters with such names are likely to be fighters of some sort.

Has nothing to do with the Theme Naming of actual weapons.

 * Elf Quest has a family with theme naming. Strongbow's son is named Dart, and Dart's son is Bowki (combining his father's name with his erstwhile friend Geoki). The line can be extended to four generations if you use "archery" rather than "weapons" as theme: Strongbow's mother was named Trueflight.
