Cousins-in-Arms (quest)

Cousins-in-Arms is a unique quest for the Wood Elves race introduced in Total War Warhammer II The Twisted and the Twilight DLC.

It is part of the Wood Elves faction mechanic to confederate other Wood Elves factions such as the Laurelorn Forest in this case. As long as the Laurelorn Forest faction exists, it can be triggered by completing the Oak of Ages (Withered) building in the The Oak of Ages settlement, the province capital of Yn Edri Eternos. It involves defeating Norsca armies in battle.

In-game description
"Nestled in the northern reaches of the Empire is Loren's sister-colony of Laurelorn, an enclave of Wood Elves that also endured the ages since Ulthuan withdrew its colonies from the Old World. The Empire states of Nordland and Middenland have historically both claimed the Laurelorn Forest as their territory, but due to the fiercely isolationist Asrai who inhabit it, none have ever tried to enforce such claims. Lately the Empire has been the least of the Laurelorn Elves' worries, as the Sea of Claws has seen increasingly frequent crossings by bloodthirsty Norscans whose sole purpose is war and destruction. Recent Northmen raids have seen them gain ground further south into Nordland, bringing Marauder bands closer to Laurelorn Forest. Minor skirmishes have already occurred, with Asrai blood endlessly spilt. For the good of the Weave, defeating the Norscans in battle and weakening their numbers may gacilitate a friendship with the Laurelorn Elves and make them more sympathetic to your cause."
