Waiting for Galadof - Mission 2 [Legends of the Ancients, Campaign 1]

Hello everyone, please tell me where to find the Sphere of Magic Amplification and the Crystal of Direction in the Tribes of the East campaign, Legends of the Ancients 1, mission 2: Expectation, and where to take them to the ruins of Castle Seraz. I've been struggling with this for two days. To be more precise, this quest needs to be completed to reach the green castle through a one-way portal.
