Ok, so I've realized I've have yet to share post-imprisoning Damarchus.
Cley makes him into a big fat wolf. It's supposed to parallel on how Asterion starts in the story as very thin and sickly, slowly shifting into a much more muscular form as you give your affection and care to him. Damarchus, on the other hand, shifts from that muscular build, to a more overweight build. Later on with the story, protagonist would learn that Cley associates with love/happiness with fat, hence its Cley giving his (platonic) affection towards Damarchus.
He's my personal favorite amongst the designs. You'd get to dress him like you can with Asterion. Damarchus hates the entire process throughout.
