Talented inventor

Exploration Stage: Shaded Patio
From: William Tarns
Description: Tell me what you want to know about Jacob and I will tell you about Leonardo. Leonardo founded the Five Wise Guardians, but I was not recognized as an official member of the group, despite the fact that I have created numerous inventions. Can you find my prototypes?
Completed: Here's my prototype. Clever, isn't it? People accuse me of stealing the Guardians' technology, but in fact it's the opposite. They used my designs and fired me. I'm only taking back what is rightfully mine!
