Ary is my fav <3 Jeih is fun to watch when he's horsing around, but Ary is so deep. He's got this huge responsibility to help Jarovin, and he is so patient and caring -- except when it comes to certain cases that really bother him, such as Hons. And I love seeing his interactions with humans. He's curious and gentle, despite being this creature that is enormous beyond what we can comprehend.
I really love all your characters, and I absolutely love Jeih and Ary, but narrowing it down I really like Aryian's character. He is a patient, calming character with not quit a fatherly personality towards Jeih, and other little noodles, but more like the friend that will always be there for you, as well as be the devil's advocate when need be.
