Title: Rumors
Pairing: Severus/Remus
Warnings: infidelity (sort of) and hints at a scar fetish
Summary: In imperial Rome, rumor can alter much. Remus tries to persuade Severus to support the extension of citizenship.
Notes: Romans of good family had three or four names: praenomen, nomen gentile, cognomen, and (sometimes) agnomen. In doing a bit of research for the names, I discovered that although "Lucius" is a praenomen, the other familiar names are all cognomens; therefore to be consistent, everyone here is referred to by his cognomen or agnomen, which were often used as nicknames. *coughs* Anyway. The general political situation was more or less as described at about the end of the second century, but I'm certainly not claiming total historical accuracy.
