Chakat Red was once the human Neal Foster, infamous as captain of the Folly.

Shi was introduced near the end of the short story To Snare a Firebird (a crossover between Tales of the Folly and The Flight of the Phoenix). 

Shortly after heading out to his colonies, some playful deities decide Neal Foster should try life on the ‘furry’ side for a while. In To Snare a Firebird we find him/hir not far off from having twins of his/hir own.

Others have been ‘processed’ by the  Folly’s transporters, but there are a growing number that have been ‘changed’ such as Chakat Blackrose who we meet in chapter 15. and at the end of Powerless we see two humans turned into a chakat and a fox vixen.
