Grundt said Besfer Village was becoming overrun with undead. He wasn't able to help, but sent you to a Protector of Divinity named Gigrite who could. You killed Pale Zombies for Gigrite. Then he said Beritra's Weapon was still turning people to undead. You asked for help from Vanargand, a mysterious animal, who told you how to summon a Whistle Spirit. The Whistle Spirit neutralised the energy coming from Beritra's Weapon, if only temporarily.
