For me personally, (of course Iflar lol), but also I would have like to have seen Taffial in the show. I think he was pretty important, especially when he discovered the City of Kehn-Sep. I would like to see what his personality is like as well. I also wanted to see Headmaster Ankhyja and more of the Royal Mipedian Academy of Melee Arts.
I know this question was probably asked already, but I feel like this forum is almost dead, especially in Chaotic Universe.
