Hermit

"Don't go down there, please. This is no place for youngsters."

- Said to prevent 14-year-old Edward's journey into the sewers

(Page Contains Spoilers)
The Hermit is one of the side characters that appear in Edward’s Sewer Adventure that is only seen for a short amount of time, but at the same time is very mysterious as to who they are.

Details
The Hermit appears to be a homeless man who decided to live down in the sewers. He was a bright green shirt and black pants and black shoes. In the Hermit's Hole we can find him resting on a makeshift bed or sleeping bag. Once you enter the room you will see that the Hermit possesses the key needed to access the Crab Lair and once you obtain it he will tell Edward his warning. The middle of the room contains an active fire and will damage the player if stepped on, which is quite obvious. There is also a Save in the room as well.

Beginning
The Hermit appeared in Edward's Sewer Adventure shortly after the beginning and ending of the game. In the beginning, we find him in the Hermit's Hole in the first level of the sewers, and he warned Edward to not enter deeper into the sewers because of the dangerous creatures that lived down there, including the Sewer Cats.

Ending
During Edward's moment of despair while his flashlight and all the lights in the sewer unexpectedly went out, the Hermit opens a manhole from above and pulls him out to greet him with his physical movements by nodding his head at him to communicate without ever talking verbally. Edward asks the Hermit if he knows the exit to the sewers and the Hermit nods, he leads Edward to a nearby exit where he reunites with the St. Andrey Detective but stays within the sewer tunnel to end. It is mentioned by the detective that he did not see the Hermit walk with Edward.

Speculation
According to the differences in the Hermit's behavior, the faint glow around him at the end, and hints from Erathor himself, it appears that the Hermit seen at the end of the game is a different entity as a whole who leads Edward to safety. It could be that the Hermit is some sort of spirit or higher being of some kind, although, nothing is for sure.
