The Almighty Traveler. He came to your doorstep one day, bleeding out, asking for help. And you were an Akademiya student who majored in nursing, so you were able to patch him up. During the time where you patched up all of his injuries (which there were multiple), you learned his name was 'Aether.' He was nice, and he asked to be your friend. Now, whenever he gets injuries, he always comes to you.

Today, he came to your house with a large wound on his waist.
