Prisoner's Honey is the preferred drug of the Neath, discovered on the Surface but now far more popular below ground. It's made from a flower called "exile's rose" pollinated by the lamplighter bee. Eating the honey physically transports the user into that mystical alternate world called Parabola.

The drug is popular among bohemians, who meet in "honey dens" to find artistic inspiration in the dreamlike realm, or to experience heightened sensual pleasures. Habitual users can become addicted, as well as susceptible to returning from a trip too early. These "honey-mazed" people are physically present in reality, but their minds and senses are still in Parabola until the drug fully wears off. The honey-mazed are not uncommon on the streets of London, stumbling around unaware of their surroundings and reciting nonsense.

Xenophon, an ancient Greek writer, wrote of prisoner's honey (he called it mad honey), but the effects on his Surface soldiers resemble honey-mazing more than honey-dreams.

The devils created Prisoner's honey on behalf of the Fingerkings, so people would be able to visit Parabola. As part of this deal, the Fingerkings owe the Devils one fifth of everything they gain.

Gaoler's HoneyEdit

Gaoler's honey is colloquially called red honey, because, well, look at the illustration. This is a more sinister breed, whose consumption allows one to experience another's memories - which is incredibly painful for the unfortunate victim. It's made from a flower that is a cross between the exile's rose and a flower from Hell, pollinated by bees that have crawled through a victim's brain. It seems the hybrid has existed since the days of the Fourth City. The name likely refers to the practice of capturing prisoners in order to harvest their minds for this valuable drug.

It's said that a contaminated batch made the Empress's children into monsters. (See The Shuttered Palace and the Empress's Court for more info.)

Those seeking their murderous rivals may prepare and take a drop of this honey, and be transported into the "Chambers of the Heart". This is a mysterious dream location where the honey consumer picks and chooses from intense, pleasurable snippets of memory, but also senses the distant victims screaming and pleading from the pain this causes. Other users of red honey are present in the Chambers, though everyone's face is obscured.

This Ambition also reveals the existence of a Cage-Garden in the grounds of the Shuttered Palace, where captives are harvested to make red honey.

Some of the red honey that is not gathered in Hell is produced on the Isle of Cats by the Pirate King, Leopold, who himself is a red honey addict. The people whose memories are used to create the honey are kept locked in cages, and are almost comatose due to the amount of pain they are experiencing. It is said that if a person's memories are used to create honey, but they escape and drink the honey containing their memories, they will be mostly fine (though they may still have some memory issues).

Several important figures across the zee are implied to be addicted to honey.

"We are democratising art," she says, loftily. "Thanks to our cage-garden, a writer need not speculate about the sorrow of a lover as their beloved dies; they can taste our honey and know it themselves. We are no longer subject to the tyranny of experience."

With Hell being off-limit, the production of red honey shifts to Titania by the Midnight Rose. Most of the red honey are created from caged artists: They can leave anytime, but they believed that to create art, one must seeks misery.
