Kyratzes Talvadore (Main Fursona) I was playing Last Rose in a Desert Garden, which was designed by Jonas Kyratzes, I've used the second name as my main fursona's first since then, and I just made Talvadore up because I liked the sound of it.
Porcius (RP/Story/Game Character) is just a generic Roman sounding name, the character Porcius is from a game I was working on set in the era of the expansion of Rome.
Kreo (Stag fursona), I just made up one day.
