One of the most societally destablising drugs ever developed, Ascomycin is an anti-agathic, which is to say, it is a drug that prevents or retards aging.

Ascomycin is a drug that confers non-specific immunity. It’s less an anti-biotic than a true endotoxin, and works to prevent nearly any disease from affecting those dosed with it – and a single dose lasts about 70 years.

The mechanism of the drug involves stimulation of the reticulo-endothelial system (the white blood cells and such). It is apparently a biological drug with multiple sources, though generally not more than one or two to a plant. The Okie ‘Cities in Flight’ use it as part of an their immortality drug suite.

Clithni is a translucent, somewhat emerald-coloured liquid that is believed to the secret of the extreme longevity of the Ganymedian people. It is a naturally occurring chemical on Ganymede (a moon of Jupiter), where it arises in geysers from the craters of extinct volcanoes. It is somewhat similar to a terran mineral water in its nature, though of radically different chemical composition.

The Elixir

Created by Ra’s al Ghul and brought to Gotham City by his servants, Whisper A’Daire and Kyle Abbott, the Elixir was intended to be sold as an expensive longevity drug, keeping those who took it young and healthy for as long as they did. It was also a potent mutagen, causing each user to develop the traits of a different animal. It was intended to sow chaos and disorder throughout Gotham, and might well have done so if no one intervened.

The Batman is, of course, all about these kinds of interventions. He identified the source of the drug, its alchemical origins, and its effects, and managed to bring A’Daire and Abbott’s plans to a stop while destroying all supplies of the Elixir before it hit the streets. And a good thing too.


Ex-Tend is an anti-agathic about which little is known. It appears to be a close relative of the drug FOREVER.

Although little is known about the mechanisms by which it works, it is known that it does not confer actual immortality, in addition to which there were claims of deleterious side effects. Nonetheless, most users are content to take it for now, and let it delay their aging until an even better anti-agathic is invented.

Ex-Tend exists in only a handful of closely-related alternate timelines or eigenstates.



FOREVER is an anti-aging drug produced by Blue Sky Inc.

Although little is known about the mechanisms by which it works, it is known that it does not confer immortality. It is available only in pull form and must be taken daily.

FOREVER is known to exist in most of a cluster of closely-related alternate timelines or eigenstates.


Forever Compound

The Forever Compund is an alchemical serum produced by the Brotherhood of the Shield. It is a diluted form of the Elixir of Immortality developed by Isaac Newton in 1652.

While it still retains the life-prolonging properties of its parent elixir, it doesn’t keep any of the other properties. In particular, it does not prevent the mind or body of the person injected with it from decaying.

Newton administered it to Nostradamus in 1652, which kept the seer alive and also kept his prophetic gifts intact until Nostradamus took the Elixir of Immortality three hundred years later.

Human Drug L

A pill produced on the island of Krakoa, the independent mutant nation located in the west Pacific, Human Drug I is a life extension treatment, prolonging human life by five years. It is unclear whether this means five years per dose, or is a singular effect that a given person can only benefit from once.

It is a naturally produced chemical grown by specialised and unique plants on Krakoa, and distributed to nations that have the appropriate treaties with Krakoa by the Hellfire Trading Company.

Lazarou is an anti-aging cream produced by the corporate interests of the al-Ghul family. It is brutally effective, as are all things produced by Talia al Ghul.


The exact translation of Miruvor or Miruvóre, is not known, but “death-defeater” is a probable etymological meaning. It’s certainly an accurate description.

Appearing in The Fellowship of the Rings, Miruvóre is a warm and fragrant clear cordial made by and consumed by the Elves. They do not reveal how Miruvóre is made, but it is thought to come from the honey of the undying flowers in the gardens of Yavanna in Valinor. It’s possible that this drink holds the secret of Elven immortality, although if so, it has no such effect on humans, hobbits or dwarves.

The cordial gives the drinker renewed strength and vitality, and is used by the Elves at their festivals. Some party animals, those Elves, huh?

Rat Tonic

Rat tonic is a healing potion for specifically intended to heal rats. It can also be used to treat the symptoms of ageing in rats. It is sold in a small red bottle at the Magical Menagerie in Diagon Alley, and presumably at similar locations elsewhere.

It is also the case that excessive use of Rat tonic can result in the rat drinking it becoming engorged, enlarged and even deformed. It is recommended that the directions on the bottle be followed to the letter.
