I finally caught up last week and honestly, the ending landed a little flat for me, though I see what the author was going for.
It wraps up with Cale Henituse, after all his scheming and pretending to be lazy, essentially achieving his initial goal of a peaceful slacker life—but on a cosmic scale. He and his family, the whole found-family crew, end up in a pocket dimension away from all the world-saving chaos. The final battle against the White Star and the God of Despair is brutal, but Cale's victory comes through his classic strategy of letting others do the heavy lifting while he coordinates and takes the symbolic final blow. The resolution hinges on the bonds he formed; it's his connections that power the final seal.
My main gripe is that it felt too neat. Everyone gets a happy ending, all loose threads are tied, and it slides into pure wish-fulfillment territory. After so much clever manipulation and near-death experiences, the quiet retirement epilogue, while thematically consistent, lacked the punch or bittersweetness I expected.
