Tin was discovered in ancient times. As bronze – an alloy with copper - it gave a whole period its name. Below 13°C tin starts to crumble - a phenomenon called "tin pest". When bent it makes a distinguished sound: the tin cry.

Stannus the monster is the guard of the king's palace. He is unable to talk with a normal voice and screams permanently. Therefore he also serves as the herald of the court and announces the king's newest laws and resolutions. Unfortunately he is very sensitive to low temperatures and thus easily catches the cold and suffers from rheumatism.

Copper was the first metal discovered by mankind. 10,000 years ago man made tools and jewelry out of it. Because of its beauty it was associated with planet venus, the goddess of beauty. Nowadays it is still being used in multiple applications. Cuperina is a lively lady and the damsel of the castle. She’s a bit vain, has many admirers and loves to dress up. But her „heart of gold“ and her sense for practicality seperates her from the other more aloof inhabitants of the castle.
