Haha...
She's so gonna be in Banished Children, there's no doubt for me.
Vendetta, Giselle and Alisa are as good as confirmed to hunt Ben, and I'm assuming Heixing and Leton will come for Carter. Kylie is likely to appear due to her involvement in the Game of Dragons and Ryo in particular, and Bibi's ties to both Alisa and Ramjist make her a likely candidate for a cameo as well.
Danny Law is a carp and closely related to the Game of Dragons as well as Carter, so he too is pretty high on my list of potential recurring characers.

Anyone I'm missing? I don't think Albus, Irene, Sion, Anne or Ray are too likely to make an appearance in person, same for Misty and the Tri-Stars. Characters like Jane and Isaac are basically bound to Wind Wall District and won't make it to the Kalter Mountains either.
