Morgan was a Cornish piebald rat with a stump for a tail and pierced ears. He served as the lieutenant of the evil god Jupiter, being his closest and most trusted follower, yet even he was not privy to his master's true identity.
Morgan was selfish and cold hearted, much like most if not all of the other sewer rats who worshiped Jupiter. He was ambitious and would do whatever it took to stay in Jupiter's good graces.
As a piebald rat, Morgan's fur was spotted. He kept an old rag tied around his stump of a tail and had an earring in his right ear.
In his youth Morgan was known by the nickname Spots, and was leader of a band of rats who served under Dahrem Ruhar of the Scale. They attacked Mulligan and Woodget Pipple in an attempt to retrieve the ninth fragment of the jade egg of Sarpedon. However, they were unsuccessful, and Mulligan cleaved Morgan's tail in two whilst defending Woodget. Enraged by Morgan's repeated failures, Dahrem cursed him to always be in the service of another before leaving him to his fate.
Eventually Morgan found his way to the sewers of Deptford where he gained favour with Jupiter, the living god of the rats there. He throttled Black Ratchet, Jupiter's lieutenant at the time, and took his position.
He was thought to have drowned in the sewers when Jupiter's great tail knocked him into the water at the end of the story during the fight between the mice and Jupiter. He is the only rat who knew fully of Jupiter's plans to release the Black Death once more, by making the sewer rats dig large mines until they dug straight into a pit used to throw plague victims into. It is also revealed that Morgan killed Jupiter's previous lieutenant in order to take his position.
Confirming he did not die in The Dark Portal, Morgan appears in The Final Reckoning leading an army of city rats who know him as "Old Stumpo." The rat army kills Piccadilly's family and friends in Holeborn. After being contacted by Jupiter, he is seen throughout the story leading his army to Jupiter's base. His last appearance in the story is when he fights Piccadilly in the snow. He later commits suicide. He makes a short cameo in the third Deptford Histories book, Thomas.
