Proper noun
Retz (plural Retzes)
A surname from German.
M. John Harrison, Viriconium, London: Millennium, 2000, p. 9 Retz has ambitions to seek treasure in the broad wastes south and west of Viriconium, and petitions the Queen to allow him to keep the power knife so he may defend himself against his enemies. Source: Internet
Retz uses a power knife, a relic of previous times when high technology was used, but which is now ill understood; the badly-functioning power knife gives off floating motes which harm the wielder. Source: Internet
