- “I am the dark thought in their waking hours, I invade their dreams and bring horror! I am the essence of night, the terror around the corner, the echo behind!”
Jupiter (born Leech) is the main antagonist of The Deptford Mice trilogy.
Jupiter started life as one of three kittens born in London to Imelza, an orange tabby cat, on the 13th of December 1664. He was a sickly runt with sable fur like his father, the mysterious Imp. The feline midwife who delivered him recommended that the kindest thing to do would be to kill the weak newborn kitten, but Imelza was horrified at the idea and sent the old cat away.
After a week of winter hardship, Imelza and her kittens were found by William Godwin, the young, unwilling assistant of Elias Theophrastus Spittle. Taking pity on the freezing family of cats, Will carried them back to Spittle's apothecary shop. Though Spittle was at first angered by the arrival of the cats, Will was able to convince him that he could make a familiar out of one of them. The alchemist chose the strong ginger male, whom he named Jupiter. The sable runt he scornfully dubbed Leech because he found him repulsively ugly. Meanwhile, their tortoiseshell sister (who Spittle took no interest in due to her gender) was named Dab by Will.
Leech grew envious of his brother Jupiter, who began to learn the magic arts from Dr. Spittle. Meanwhile, Spittle would abuse Leech, taking out his anger on him.
After Dr. Spittle had imprisoned the spirit of Magnus Augustus Zachaire in a bottle, Leech learned the magic arts from him, despite the fact that only Jupiter could use it at the time.
But finally, when Dr. Spittle's apothecary shop was burning down, Leech tossed Jupiter down a burning chimney and the cat fell to his death. After this, Leech took Jupiter's name. Beckett led the badly-burned cat down into the sewers, where he crawled into the dark portal and (because he drank from the elixir of life) he was able to remain there for centuries, worshipped by rats.
Role in The Dark Portal Edit
- “All these years, all this time I have lain hidden and secret from my subjects. Think of it - a cat worshipped as a god by rats!”
- ―Jupiter to Audrey
Over three centuries after initially crawling into the portal in the sewers, Jupiter reigned supreme over the rats of Deptford, worshipped as their living god. None had ever seen him, for he dwelt in the shadows of the portal and only his glowing red eyes were ever visible. However, when Audrey Brown confronted the evil cat and threw her mousebrass at him, he fell into and drowned in the sewer water.
Role in The Crystal Prison Edit
- “I must escape. You must help me, I must return to the fields ere I perish for eternity.”
- ―Jupiter to Akkikuyu, as Nicodemus
On a hot day in Deptford, a terrible stench hung in the air. It was strongest at a building site near the River Thames. One of the human builders discovered the source of the foul odour - the rotting body of Jupiter, whose corpse washed up from the sewers. The man who found him lifted his grisly discovery with a shovel and tossed it into the building site's bonfire. A thick, dark smoke rose from the flames and hung over Deptford for two days before a summer breeze blew it away on the third morning.
Meanwhile, trauma-induced amnesia prevented Madame Akkikuyu from remembering Jupiter or any of the events in the sewers of Deptford. Then a mysterious voice began calling to her at night. Only she could hear it and it tormented her. In Fennywolde, the voice finally revealed itself to Akkikuyu as coming from the tattooed face on the rat's ear, which was now animated. It claimed to be Nicodemus, a spirit of the fields trapped in limbo. He begged Akkikuyu to help free him. When the rat agreed, it was revealed that Jupiter wanted to take over her body since his was destroyed. Akkikuyu tossed herself on the fire before this could happen, though.
Role in The Final Reckoning Edit
- “He is now an Unbeest - an unquiet spirit not governed by the rules of the living. His presence in our world has thrown into confusion all the old prophecies.”
- ―The Starwife, about Jupiter
Unfortunately, this enabled the spirit of Jupiter to return. When Alison Sedge broke Akkikuyu's crystal ball, Jupiter was free. Wanting revenge, he smothered the world in an eternal winter. He stole the Starwife's Starglass, and used this to remove the stars from the sky. He planned to remove the sun the next night, but before he could do anything else, however, Audrey confronted him once more. She threw a snowdrop flower into his mouth, and this condemned him to the doom of life throughout eternity.
