My version of the archangel Raphael.
The Heavenly Senior Physician runs more or less all medical facilities in Heaven. Although he's very busy with that, he also finds the time to come to Earth and endulge in a bit if hiking and protecting wanderers on their journeys.
He may look like a very serious guy on the outside, but he actually loves to play pranks on people who can take them. Another thing he does in his limited free time is caring for a garden with Uriel. He has a large collection of healing herbs growing there. He's also got a large fish tank in the garden.
