Wanderer Sabaku met me at the foot of his mansion’s grand double stairway on the Diabolos server of Final Fantasy XIV. He was nearly twice my size and towered in a purple floor-length coat. A crown sat on his blue-gray head. He welcomed me from behind a partition and led me down some winding stairs into the basement, which opened onto a theater. It was his theater, where, on December 30th and 31st, he will direct a full-scale, in-game production of “I Want to Be Your Canary,” a play from Final Fantasy IX.
