Hi, I don't know if anyone would know when more content would be added to Arion or Tank, if not Jester are my favorite characters.
Arion is a guest author content, so Hyao doesn't write about him, but includes the new content when the fuest author has new ideas, while Tank and Jester are linked with Northcrest and the orc's war and since Zoroj is the one drawing for this storylines and since he's on a break i suppose for now there will be no nwe content about them. Take in consideration that this are only suppositions
