Sullustia Furia is a Roman Priestess of Senatorial family. She is unmarried. She fled the Roman Empire when she was suspected (correctly) of practising magic, which was illegal in the Roman Empire. She now wanders the Fifty Worlds.
Sullustia Furia and Ylyema ay-Lupu are rivals. Although they are happy to cooperate in any lawful good cause, they are even happier when competing against one another.

Priests and priestesses of Minerva are permitted to use edged weapons. Sullustia Furia usually uses a gladius and has attack bonus +1 with that weapon. She regenerates 1 hp/turn. Once per week, she can, by meditation, determine the correct answer to any one question with a simple one-word answer (usually either yes or no).
Since Minerva is patroness of musicians, Furia can cast spells from the school of song magic as well as from the priestly spheres. Mass suggestion is particularly effective in gaining converts to the faith.
Furia's primary duty is to bring the Cult of Mars into disrepute. Ideally, she should humiliate priests and worshippers of Mars in public rather than kill them. But if that can't be arranged, killing them is OK too.
Furia is required by her religion to remain celibate and chaste (these are technical terms with specific meanings which you might wish to check).
Sullustia Papinia, a gladiatrix, is Sullustia Furia's minder. She is Roman, with no birthright. Papinia was bought and freed by Sullustia Furia and took her family name. She is entirely loyal to her patroness.
Papinia specialises in fighting styles which use the gladius.

Papinia has the hit point bonus (already included in the listed total).
Papinia remains celibate by choice. She is required by her beliefs to remain chaste for the five consecutive days around the Spring Equinox when both the Cult of Minerva and the Cult of Mars hold their most important festivals.
You want trouble? Start with a Temple of Mars. Add Sullustia Furia, stir for a while, and then bring to the boil.
Note that although the Legends and Lore listing for Athena will do well enough for Minerva, the Legends and Lore listing for Ares is entirely wrong for Mars. Mars was more of a neutrally-aligned male fertility deity. His priests are probably druids.
