Opa Wetterwachs was the first player ever to reach lvl 50, way back in the beginning. When everyone was around level 40, he was level 60+.
Lostboy created Fibula Village, Tower Flat for him while creating the island of Fibula, a building which is therefore also known as the Opa Wetterwachs Tower. It is said that Opa Wetterwachs summoned and killed Dragons inside the tower's basement that has since been removed.
