As the dralasites are thoughtful and philosophical.  As the vrusk are hard-working and practical.  The sathar also have traits that nearly all of them share to a great degree.  In fact, they have three.

Sathar spend their lives sure, convinced even, that they are part of something greater than themselves.  Whether it is their tribe, their calling, their sect, or even their faith.  Usually a combination of the previous, in fact.  The "loner sathar" is pretty much a contradiction in terms to them.  This sense of belonging helps them feel that everything they do has a greater purpose.  Even if they may not know what that greater purpose is?  They still have almost complete faith that they are playing their part in it.

The Great Worm calls on its Followers to be ever alert for signs of the unclean, the impure.  No sathar is immune to becoming fouled.  Not even the disciples themselves.  Only through remaining ever watchful, vigilant, can they not only spot the taint in others, but guard themselves from it as well.  Now because of the closeness found within the tribes and sects, such vigilance tends to be directed outward, instead of inward.

Once the disciples have judged a sathar, a tribe, a sect, or even an entire race, as tainted?  Most sathar will believe it with every fiber of their being.  There is no doubt.  There is no mercy.  The strength of their convictions carried them through their race's darkest days.  As their beliefs will carry them through whatever is to come.

However, what if the disciples have not judged?  If the sathar, tribe, or sect, was so convinced that they felt no need to wait?  Then the result can be very bloody indeed since the accused, and their allies, will believe in their innocence just as strongly as their accuser, and their allies, will believe in their guilt.
