This rite is performed before peaceful meetings between different tribes. The Garou involved in the meeting must recite specific oaths as part of the rite; the oaths are short and simple and formed as a command. ("None here shall raise claw against another"; "Each swears to defend the honor of the other"; "No lies shall pass our lips"; and so on.)
All the participants in a meeting must perform this rite just before the talks start. If all do so it becomes more difficult for them to frenzy as a reaction to on another's actions (one extra success on a Rage roll is required), for so long as all adhere to the oath. If broken by a single member, though, the pact is void.
