One of my projects is to have comprehensive references to each of my characters — body-wise, personality-wise, history-wise, and so forth. Here’s the scrap I have so far on our traveller Periont.
Body—
His adult height is about five foot seven, ears excluded. He is of a moderate build, slightly tending towards lean and muscular, and weighs in at about one hundred sixty pounds, tail excluded.
Age—
Periont around the time of his story is a νεανίσκος somewhere in his lower- to mid-twenties. This is apparent from looking at him—his features are mature enough that he is certainly no longer a teenager, and while the salt-and-pepper fur he has in places might give an initial impression of aging, he is otherwise youthful enough that he couldn’t pass for over thirty.
