“‘I, Bade of Underling, god of war, swear a salt vow to Matilda, the herald of the gods. I will be her loyal ally and will never betray her. I will aid her whenever she is in peril or in need. I will instruct her on how to fight and defend herself, until she becomes like iron. Should I break this vow, she has the right to end my immortality, and my name will be disgraced.’”
