Standing before the Golden Stone, Rin and Ingard did as instructed, relating the words of Wolfram advised them to.
Then they got transported into their own minds. More words bellowed and loyalty, asking them to answer with their might if they would abide by the rules of Black Wolf Settlement.
The rules have never been complicated. They can't harm their fellow members, they can't do anything Immoral that brings destruction to the sect, they can't tell anyone about the Golden Stone and its advantages, and a few other matters.
Are these even considered rules?
Ingard and Rin, who came from an influential sect, felt that these rules were child's play and quite simple and understandable to follow.
They willingly swore oaths in this regard, promising to abide by all rules.
One can see that there's a lot of freedom in the way the people of Black Wolf Settlement operated and lived.
