Presea, the Master Smith in the Forest of Silence Episode 2

Guided by Clef's words, the girls reach the Silent Forest and find a fortress-like edifice. They meet Presea, the owner of the castle, who confirms that only a Legendary Magic Knight could have gained entry. Presea has them choose their weapons, and instructs them that the weapons will appear only when needed. But they must bring them to Eterna Lake to pick up a mineral, Escudo, which will bring power to their machines. Before they leave the fortress, they are forced to use their wiles and their new gear to defeat a monster. Mokona, a friendly creature from the fortress, guides them to the Lake.
