Tofa said there were problems involving the Ice Claw Mau. You met Aprily and Jorund and found out that the Ice Claw Mau were worshipping an Artefact Protector, which had changed them a lot. You killed a White Brow Tayga and gained the ability to enter the Aetheric Field. You defeated Protector Karhel and reported to Brigade General Aegir.
