Speak with Architect Liath in Lake Liath.
On your journey to obtain Lagon's blessing for the Lance of Heorot, you, Grael, and Yulia made your way west on different paths through Lake Liath towards Thetima.
After traveling through Lake Liath, you found yourself in the shadow of a massive tower. You participated in a battle between its defenders and the forces of Rahyeh. After defeating the invaders, a woman appeared in an eruption of water and lightning – the mistress of the tower, Architect Liath.
