Sirius

Sirius is the name Humans use for the god of protection and justice, perhaps best known for being Black's patron god. She also has a sizeable organisation dedicated to her.
In the absense of Pelor (long story), she has taken the role of the main "god of good" in the TDDC setting.
Priests of Sirius often take vows of chastity so that they will not be tempted to protect specifically their families rather than protecting everyone. This is, however, optional.
