Times of Lore

To enter Heidric's castle in Ganestor, go to the cellar of that town's inn. On the north wall you'll find a small, barely visible lever. Bump into it, and a secret stairway will be revealed.

The Tablet of Truth is toward the center of the castle's ground floor. Avoid engaging any guards, as you'll need to return here later in the game to speak with Heidric. Before returning the Tablet to the Regent, Use it and choose High King.

Unlike the Dagger, the Magic Axe automatically returns to your hand after each use. It makes combat much easier and faster.

To purchase the Magic Axe, go to Lankwell and enter the building in the NNW corner. If no one is home, wait for them to arrive. Upon meeting them, immediately choose the Speak command, and they will offer to sell you the Magic Axe.
