The Howling Knight's homeland was lost centuries ago to entity encroachment. Rumors and legends tell of the Howling Knight's homeland clinging to the cliffs beyond Bridge Keep. Now abandoned to all except the brave and foolish, all the ancient kingdom had fallen into decay or the chasm.
He patrols known noclip points, looking for travelers in need. It's his quest to see travels in distress (due to Backrooms entities) make it safely to civilization.
Some older travelers of the encroachment, know the Howling Knight less formally as Howlin Hank Whittacker.
The Howling Knight often gets asked how to get back to Earth. That puzzles him and constant confusedly calls "Earth" (AKA the Frontrooms) "Dirt". He considers "Dirt" a stupid name for a Backrooms level, and loudly proclaims that frequently. Even while calling "Dirt" a stupid name, he'd die before letting entities encroach on the last level that humanity thrives.
Many have asked the Howling Knight his age. His standard responds with, "I died centuries ago." He never explains himself further, and few dare ask further questions because of the dark mood this topic puts him in. Some speculate that due to the non-linear aspect of time in the Backrooms that he already know when and where he will die, and it literally is centuries ago. Others speculate that he refers to the fall of the old Chasm Kingdom that fell to entity encroachment centuries ago.
