The Story of My Grandfather location (Glass Lotus Lake)

Clue

A group of young Sylvains are gathered around and talking about how great their families are, and among them is a kid with a sullen look who's being made fun of by his friends. "There's no one famous in the Behender family!" "That's not true! Have you seen my grandpa? He's amazing!" "Hmph, your grandpa does nothing but lie around Glass Lotus Lake. What's amazing about that?"

Story

Tears started welling up in the young Sylvain's eyes, his heart broken by the cruel jests of his friends. Just before the tears could come trickling down, a big shadow appeared from behind the tormenters. "Take a seat, kids." Everyone turned their heads, and there was an old man standing behind them. "I'm going to tell you the greatest story you'll ever hear in your lives. Guaranteed." Secretly giving his great grandson a wink, he started to tell a story with overly exaggerated gestures.
