Aretha Franklin

Aretha Franklin defined the sound of soul for over half a century. While her voice moved millions, her private life and unique habits often remained behind a curtain of mystery. For instance, she refused to set foot on a plane for the last thirty years of her life. Furthermore, she collected academic honors with the same ease that she collected hit records.

Saladin

Saladin transformed the medieval world through his military genius and his reputation for justice. While he famously recaptured Jerusalem from the Crusaders, his life off the battlefield contained surprising acts of kindness and a deep love for learning. For instance, he once sent fresh fruit and ice to his greatest enemy during a fever. Furthermore, he died with almost no money because he gave his wealth to the poor. Prepare to meet the Sultan who earned the respect of his enemies.
Owls

Owls rule the night with specialized biological tools that no other bird possesses. While most people recognize their haunting hoots, these predators hide incredible superpowers beneath their soft feathers. For instance, some species hunt in total darkness using only their hearing. Furthermore, they can rotate their heads almost in a full circle without cutting off their blood supply. Prepare to meet the ghosts of the forest.
