You don't hear as much about the Seven Virtues as you do about the Seven Deadly Sins. It's probably because the virtues are rather passive or long-term. Chastity, Diligence, Charity, Temperence, Patience, Humility and Kindness are much harder for us to characterise than Pride, Wrath, Greed, Sloth, Envy, Lust and Gluttony.

PPS - Not much does, though. That's probably why there never was a sequel.
