After the Shattering, the Concord was the non-aggression pact signed between the Seelie and Unseelie fae "for the duration." The Concord was largely due to the willingness of the Seelie and Unseelie trolls to fulfill their duty towards the other fae. The involvement of the Brotherhood of Thor was particularly instrumental to this event.
