What is the difference between the aristocrat style and the inventor style?
The aristocrat always carries a noble title (Lord, Lady, Baron) in front of the name; the inventor has no title at all, but gets a mechanical epithet as a subtitle instead (from a 42-entry list, like "the Machinist" or "of Brass and Steam"). Both draw from the same pool of 137 Victorian first names and 111 industrial surnames, only the extra piece differs.
How does an automaton designation like "ZYGO-One" get built?
It joins a technical prefix (60 options, mostly abbreviations like VOLT, THERM, PIST) with a numeric or Greek suffix (35 options, ranging from "-VII" to "-Omega" to "Model D"), plus a functional role as a subtitle, chosen from 30 options. It is the only style with no human first name or surname.
Does the adventurer codename always reveal the character's real name?
Yes, by default: the main name is one of 40 fixed codenames ("The Iron Kite", "The Steam Leopard"), and the subtitle shows the civilian identity as "a.k.a. First Last", drawing on the same Victorian-industrial pool used by the other 2 styles with human names.
Are the masculine and feminine noble titles interchangeable?
No: they are two separate lists, 21 masculine titles (Lord, Sir, Baron, Duke) and 16 feminine ones (Lady, Dame, Baroness, Duchess), and the generator rolls gender first (50/50) to pick the correct list before matching a first name, so "Lord" never pairs with a first name pulled from the feminine list.
