We modify transchromatic character maps of the second author to land in a faithfully flat extension of Morava –theory. Our construction makes use of the interaction between topological and algebraic localization and completion. As an application we prove that centralizers of tuples of commuting prime-power order elements in good groups are good and we compute a new example.
