Castigia, while one of the less powerful gods, gets a great deal of attention because he is the Gatekeeper of Heaven and decides the fate of mortal souls. He appears as a man of indeterminate age in white robes with a quill pen and a book that he uses to keep track of all of the deeds in a man's life. If the books are balanced in his favor, the man is allowed into Heaven, if not, then a hearing is held wherein spirits of the departed are brought to the witness stand to testify to the man's worthiness. A cross-examination between the defense and a devil's advocate (here in a very literal sense) reveals all of his deeds and misdeeds and Castigia then renders his verdict.
For the most part Castigia has a favorable disposition, so those who at least made an honest effort at doing right in their life are usually allowed entry into Paradise. However, Castigia is also a proud god, and judges harshly those who slight or blaspheme him in life.
