Celestine VI

Abbot Brrteet'k was a highly evolved dolphin from beyond the Rakash Nebula who was appointed Pope Celestine VI by Brotak, who claimed authority from Constantine I.

Celestine VI and Urban XII were a rival Popes to John Paul XXIII in the 28th century. Despite dolphins being mammals, Pope John Paul made an article of faith that declared them to be fish. (PROSE: Companion Piece)
