Threshold Magazing issue 9 - Hollow World

The Mystara RPG setting has a magazine devoted to it called Threshold. Issue number 9 is devoted to the Hollow World part of that setting!

The new issue of Threshold, the fan magazine entirely devoted to the Mystara setting for Classic D&D, is now available for download (of course for free). Here is the announcement from one of the editors:"I'm very happy to announce that Issue #9 of the Threshold Magazine is available now from the Vaults of Pandius! In this issue we cover the Immortals and their Hollow World playground that was first introduced to us by Aaron Allston back in 1990. Argentmantle delves into the unique culture of the Icevale Elves, and Geoff Gander explores the history of Selhomarr. The life cycle of megaliths is unfolded before our eyes (as told by LoZompatore) and the Signs of the Universe (by Sturm) are laid bare.... and so much more. A heartfelt thank you goes out to all those who answered Threshold's call for support - we have some new names on our team as well as many of the ones you are already familiar with. I would also like to take the opportunity to thank julius_cleaver for stepping up to the plate and taking on the role of editor-in-chief for our next issue - Elves! Thank you to all of the contributors and Threshold staff that worked on this issue. I'm very proud of the material that we have turned out, and I hope that you enjoy reading through this issue as much as we enjoyed putting it together. As always, feel free to use this thread to send us comments and feedback on this issue.
Happy reading!

Dungeons & Dragons: Warriors of the Eternal Sun

Warriors of the Eternal Sun was a video game developed for the Sega Mega Drive that takes place in the Dungeons & Dragons setting of Mystara's Hollow World.

Golarion is Hollow

Pathfinder's world, Golarion, is hollow just like TSR's Mystara. Dungeons & Dragons' setting of Mystara was given the hollow world treatment with a box set and a few modules. It appears Paizo's setting for Pathfinder may someday receive a similar treatment.

This is from Pathfinder Gazetteer (page 39 and 40 under the Mammoth Lords) and is repeated in the Pathfinder Chronicles Campaign Setting book:

"Incredible rumors suggest that the beasts that make the realm famous somehow emerged from an impossible underworld with its own false sun, a savage microcosm in which the dinosaurs never died and humans never emerged from their primitive origins. The Pathfinder Society has mounted five expeditions to this rumored inner world, but none of (sic) have ever returned from the country alive."

The Campaign Setting book adds a bit more while describing the Golarion version of the underdark- the Darklands:

"Some are said to be so huge that they are themselves inverted worlds, that the denizens walk and live along the inner surface of the vault in defiance of gravity, and that their skies are lit by a glowing orb of brilliance akin to the sun itself floating at the immense cavern's center."

As a fan of the D&D Hollow World setting, I really hope to see more of the inner world of Golarion developed. We'll be watching for it.
