Professor Scheele

Professor Scheele is an ornithologist who became a leader in the city of El Dorado.

Early life
Professor Scheele was in the Peruvian rainforest, searching for a new rare species of Condor. By chance, he stumbled onto the city of El Dorado. He was chased and captured by the natives. However he found out that the same condors that he was searching for were dying from a viral disease. The condors were sacred to the natives and their city could not survive without them. Scheele was able to heal the birds. The natives, out of gratitude, spared his life.

Professor Scheele stayed in the city and had a family, presumably taking a wife and they had one son together. Scheele became a leader in the city, wearing a ceremonial robe and golden Condor headpiece.

In the Realm of the Condor
Estella recruited Dr. Quest to help her find Professor Scheele, claiming that she wanted to find out what happened to her grandfather. Dr. Quest becomes intrigued by an item she has him examine, and agrees to go to Peru to look into Professor Scheele's disappearance.

Once at the city of El Dorado, Estella revealed she was not interested in Scheele and only cared about taking the gold from the city. She held a boy hostage to try to get out, but she ended up falling to her death.

Professor Scheele tells the Quest team that Estella wasn't his granddaughter, as he only has one child - the boy Estella held hostage.

Scheele arranges to help them get the Quest team safely out of the jungle. The Quest team promise him that they will keep the secret of the city so that he and the natives will not be bothered by greedy treasure hunters like Estella again. Scheele summons the condors, who carry the Quest Team safely away.
