Lord Kalvan of Otherwhen is a great science fiction novel by the one and only H. Beam Piper. Yeah Piper. The guy who gave us Space Vikings (without which Traveler would be oh so much poorer). He also wrote about the Paratime Patrol and created a series of stories that explored the inner workings of a truly Trans-Temporal Civilization. One great example is his story Temple Trouble. That one short story would make a great RPG-scenario. The Paratime Patrol and its heroic efforts at preserving Civilization within a tangled maze of overlapping and inter-penetrating/Inter-dependent Alternate Histories is a lot of fun, very engrossing stuff. It is every bit an equal to Poul Andersons' Time Patrol , a good comparison of the parallel series can be found here.
Piper wrote the Little Fuzzy, Oomphel in the Sky, Omnilingual, and the wonderfully understated He Walked Around the Horses, which dealt with the extremely mysterious and as yet unexplained disappearance of Benjamin Bathurst -- you can get a copy of this story from Project Gutenberg. Piper also wrote some other great stories, including some of the better stories dealing with a Galactic-scale Federation and Empire ever written. But for now, we'll focus on Lord Kalvan of Otherwhen.
Lord Kalvan of Otherwhen is the story of Calvin Morrison, a Pennsylvania State Trooper who is suddenly transported to an alternate universe. That would be the 'Otherwhen' in the title. This new universe is a mostly medieval-style place where a greedy and spoiled bunch of priests have a monopoly on gunpowder. Yah gunpowder. This isn't just another Connecticut Yankee in King Arthur's Court. This is a prime example of how one person can really, truly transform a setting, society or entire world through a little know how and some old fashioned hard work.
The priesthood of Styphon are using their stranglehold on the supply of gunpowder to suppress the populace and to maintain their power base. Calvin, renamed a more medieval-like Kalvan, sets about manufacturing his own gunpowder, thus upsetting the proverbial apple-cart. He makes some serious enemies amongst the gunpowder-priests and nearly gets assassinated for his troubles. Oh and a princess takes a shine to him along the way. Oh and there's politics involved beyond just the priests--neighboring petty kingdoms are all too eager to squash this upstart Kalvan in order to prevent his heretical uprising from spreading to their lands and their populations like a fever that needs to be quarantined or cut out immediately.
It's a rip-roaring yarn of High Alternate History Adventure of the best sort, written by a master of the form in his prime.
What's The Big Deal?
Simple--Piper wrote a great Fantasy story that challenged a lot of precious, preconceived notions like the utter BS that the introduction of gunpowder somehow destroys fantasy. It doesn't. Guns don't kill fantasy, poor planning and bad writing do. Early forms of gonnes and the introduction of gunpowder is more often than not terribly mishandled in most RPGs, but that is the fault of the designers, the writers, the GMs/DMs and hardly the fault of a bunch of inanimate objects. If it's handled right, gunpowder can work alongside the usual fantasy tropes. Piper shows you how to handle it in an extremely realistic, workable and intriguing manner that doesn't ruin anything, but instead adds tons of depth, really complicates the political aspects of a setting, and injects whole bunches of conflict and bucket-loads of opportunities for adventure.
Piper also manages to introduce the 'Displaced Character,' as a model for a type of Player-character, and gives us a whole new scheme for Alternate Universes, time travel and leads into some aspects of reincarnation while he's at it. In the same book. He certainly didn't stint on the ideas. Neither should anyone engaged in a pursuit like writing, or a hobby like role-playing that is founded upon the Imagination.
