Back to Back on Hyperborea - The Late Trapper's Lament By David Prata & B2 Keep on the Borderlands by Gary Gygax - Low Level Adventures on Hyperborea

 “You there, marines! I have a task for you. Come earn your keep, dogs.”

"Your party has accepted work as marines aboard a cog called Otherworldly Obelisk. The ship has berthed in Ragnarrheim, a Viking town of New Vinland, with plans to continue to Port Zangerios, but some of the expected cargo has not arrived. The local trapper was due hours ago with a bundle of valuable ermine pelts. His tardiness is uncharacteristic. The captain orders you to locate the late trapper and, more importantly, return with the pelts, but something is amiss out in the hoary wilds of Hyperborea."

So what are the ramifications of the Free City of Greyhawk in a solar system where  Hyperborea floats near Saturn & Greyhawk sits next to the star Jupiter? I began to think about this far future solar system of mine millions of years in the future  where Jupiter is a small star. Greyhawk orbits around it & Hyperborea is near one of the sixty two (sixty three?) moons of Saturn. Greyhawk's golden age might have been in fact much more marked by the passage of Ragnarok. Humanity was led to the safety of Greyhawk because of the sacrifice of the deities of Old Earth. This was eons ago and your actually a low level adventurer whose deeply into Ragnarrheim, a Viking town of New Vinland, with plans to continue to Port Zangerios. And here the PC's get embroiled in the adventure plot of The Late Trapper's Lament. This brings them deep onto the shores of Ragnarrheim and we get a really solid overview of the village/town of Ragnarrheim.Now if the events of The Late Trapper's Lament which is an adventure for 1st to 2nd level PC's. The B2 Keep on The Borderlands kicks in with the Borderlands fort being on the outskirts of Ragnarrheim.

The Cult of Chaos has been kicking it's heels up around the town or village of Ragnarrheim. They've been bringing in agents of the cult to stir the powers of the Caves of Chaos once again. The lizardmen around the keep know what's happening and are not happy about the hermit and his ilk coming into the area and stirring up the dark forces. 

 So what this does is allows the DM to tie in the forces of Chaos into the backstory of Hyperborea without ignoring the events of the   village of Ragnarrheim. We've already got our agent of the cult of Chaos within The Late Trapper's Lament. And so this kicks events up within the trading post of the Keep. Everything from here centers around the PC's putting down the Caves of Chaos after the The Late Trapper's Lament adventure. 
This allows the DM to have two lower tier adventures ready to go on the trot with a Hyperborea rpg twist. The keep is only active part of the year and the rest of the time hunkers down for Winter. The Caves of Chaos are stirring to life once again because the humanoids are on the war path under the caves's influence. 
Five Reasons Why A Combination Hyperborea Campaign Works: 

1. B2 The Keep on the Borderlands isn't that well known to modern players at all. 
2. The Keep establishes itself as the heart of a campaign and the PC's headquarters ready to go. And after the job of The Late Trapper's Lament ends B2 picks right up. 
3. The  village of Ragnarrheim is perfect as a home away from home for the wilderness of Hyperborea providing the PC's with resources, supplies, and even hirelings 
4. These two modules work very nicely together with ships to take the adventurers onto thier next missions and a ship for down the road of adventure. 
5. The lower tier adventures don't mean that these are not lethal at all or that the Hyperborea rpg Weird Tales element is missing.
