When the heroes next returned to the King’s castle they also met with the shadow council. They did as much research as possible on many different things. Long story short it turns out ones of the members of the shadow council had fled. He is also the one that was suspected of giving the shadow council the knowledge of destroying contracts.
The heroes located him and questioned him. As it turns out he was just toying with the shadow council.
The group also learned some information by a meeting that was arranged with the ancient witch who signed the first contract. It turnes out she wasn’t a witch at all, but a hag, a powerful magic creature, who were originally known as healers and spiritual guides, capable of granting powerful blessings. It wasn’t until humanity started turning against the magical creatures that they took on the negative conotation of being evil.
