Against the Wilderness
The Swordpact of the Aldori is the code to which all potential Swordlords must swear to uphold before they can officially start to learn the style of the Aldori Dueling Sword. (In game terms, this means before you can take any feat/Prestige Class pertaining to said sword).
Benefits of swearing the Swordpact include elevation to the status of minor nobility and access to the resources of the other members.
While nobody who has not sworn it knows exactly what it entails, most people know the Aldori Swordpact has something to do with pledging oneself to the protection of Rostland and obedience to the Council. The Council is the governing body of Restov, in addtion to acting as the Noble House for the Rostlander area.
