Ahem. Yes. I do tend to wander aimlessly. But this is interesting. See, I went to the humanmetrics site and I took the personality profiling test seven times for each of my characters (dragons included), and I got the following results. All of which seemed very accurate. (though Sanlivon really could be an istj like his dad, he's borderline)
Santia ISTJ (11/12/75/89)
Okath ESTP (67/38/12/78)
Sanlivon ISFJ (67/12/12/22)
I found the results to be very telling. Or at least I found the extensive information that comes on each of the personality types to be very telling. I see a bit more about what makes my little duckies tick. Plus the comparisons between other personality types at the bottom of each description page was fun. For example, this is Melanthioth's: http://typelogic.com/entj.html
And suddenly he gets a lot scarier...
Anyway, to the point. I was wondering what all your characters would get. So, I invite you to try it as well. http://www.humanmetrics.com/cgi-win/JTypes2.asp
That's the test. Let me see how all these characters fit together...
And for the record, I'm an INTJ (89/12/1/44), or possibly INFJ. I can go either way. (only 1% T, after all)
