As in actual celestial being of myth who watches over Matt Murdock's life.

Any details (if Matt knows he's there/can sense him/has no idea/Foggy actually goes to college with him as his bff etc) up to the filler though I'd prefer if it's not Foggy pretending to be human and keeping it from Matt (though he can still pretend to be human for others if you want to take that route, I just don't want secrets if that makes sense).
