Spoiler I haven't actually read the raws or anything, but these are my opinions: The whole conflict with the Radiant Church took place about 2000 years ago. He killed the leader, and all the leaders and everybody responsible were killed as well. It's a conflict resolved and left behind long ago. I don't even know if the Radiant Church exists anymore. So it's highly unlikely that he'll be involved with that in any way anymore. As for another animal companion, again, highly unlikely. Since only this and two books are left, he just doesn't have the time or interest, imo. Haru always played second fiddle to Bebe and was left behind easily, so I really doubt that there will be any real companion. As for Reisgem, the amethyst lion, he's also a commander of the Planar War, and probably a bit stronger than Linley at the moment. He only helped Linley out because a Sovereign told him to. We might meet him again, but him becoming a magical companion is basically impossible.
