Tell me a little more about how this works please.
Let me go grab my FS book, so I can see exactly how this goes, so I don't set it up wrong.
At character creation, you pick one of each pair to be your primary stat for that pair. That score starts at a 3, the other starts at a 1. The two combined can't add up to more than 10. Most people will tend to have a few points in these, though they're not usually as high as the regular scores. If you get a bonus to one of these so that they combine to be over 10, one of them has to go down.
A person with a high Passion tends to have a fiery personality. They're emotional, react strongly to their environment, and really CARE about whatever they're currently involved in. Kirk would be an example of someone with a pretty high Passion - he gets emotional more than is really good for him. It tends to be used for inspirational and charismatic checks.
Somebody with a high Calm doesn't get riled easily, if at all. They might not be able to get deeply emotional. It's mostly useful for remaining cool in a firefight, as well as various mystical chicanery.
Someone with a Passion and Calm in the middle ranges can switch back and forth, or choose what face to display. Someone with low scores in both can't muster extreme emotion, but probably doesn't hide what he has very well.
Faith vs Ego measures how the character relates to institutions. Someone with a high Faith will tend to put his trust in structure, most often the Church or his lord. They look outside for inspiration. A person with a high Ego looks inside himself for his answers. They don't tend to care for structure, or put their faith in it. Faith rolls, obviously, are mostly used for theurgic rites (cleric magic, essentially). Ego rolls are mostly used for psionics, which tend to be a pretty self-centered art in FS. It's similar in concept, but IMO more elegant, than the Law vs Chaos divide in D&D.
Introvert vs Extrovert is just what it sounds like. Someone with a high Extrovert enjoys the company of people, and doesn't like to be alone. They're not necessarily likable, though - the boorish noble who nobody likes might well have a high Extrovert score, if he NEEDS to be around people. In FS terms, he has a poor Charm skill, and maybe a disad like Braggart or Boor. Target numbers are almost always Stat + Skill, with a d20 roll determining success. You try and roll as high as you can without going over your target number.
An Introvert prefers to be alone. Introvert rolls are usually for introspective, personal things, like writing and meditation.
The difference between the FS opposed stats and Pendragon's is that Pendragon's are, essentially, a measure of sin. I don't have a problem imagining any coupling of the three stats into a heroic person, but if someone is universallyon the side of sin in the Pendragon system, they're probably just evil.
