In Search of the Holy Grail

Exploration Stage: Mansion by the Canal
From: Cardsharp
Description: If you don't find the ice sculpture with my diamond hidden in it, it's no different than if you lost the game! How dare he do this to me! Hey, there's a chalice made of snow over there. Maybe there's a gem inside. Let's check it out!
Completed: Hey, there is nothing in this chalice. Come to think of it, I once heard a legend about a cup with the same name as this one. A king put the souls of his loyal knights in a cup and drank from it every day. He drank from it every day to prevent it from being poisoned. In case they were poisoned, the cold air of the afterlife would emanate from it. Spine-chilling, isn't it?
