lucky number

Exploration Stage: Borderland
From: Mr. Black
Description: I think Woodville is being too hard on this Mr. Ollie person. I know it's an odd way of doing things, but she is reaching out to me. She says she will tell me my lucky number if she can find the oracle's dice. Can you please help me?
Completed: I was amazed. Using this oracle's dice, Ollie determined that my lucky number was "5". This means that I have a secret lying inside me that can be unlocked through meditation. I will definitely give it a try at some point!
