Terror roams the dark and brambled paths of the Kryptwood. A pack of giant spectral hounds rule the night, savaging those foolish enough to brave the forest. The villagers of Hendenburgh cower in the shadows of the ancient boughs as each morning heralds a newly savaged corpse. Explore the ancient paths of the Kryptwood in a 25-hex hexcrawl. Discover the mysterious Tyrant's Tomb. Negotiate, serve or betray the factions of the Kryptwood (a ghostly despot, a gang of highwaymen with excellent PR, a horrifying witch coven, and the eccentric inhabitants of Hendenburgh). Fight new monsters such as owlboars, kryptwood hounds and ghostly tyrants. Hounds of Hendenburgh is designed for use with Cairn by Yochai Gal but compatible with other OSR systems. If using OSRIC, OSE or other OSR rulesets then the adventure is best suited to low-level parties (1-3). Reviews Hounds of Hendenburgh is an adventure brimming with potential energy, like a domino run—any prodding by the players is sure to set off a chain reaction, but where any individual piece will end up is anyone’s guess . . . For me, Hounds of Hendenburgh is a major highlight of A Town, A Forest, A Dungeon. I’m eager to bring it to the table, and I expect it’s the sort of adventure that will reward referees who run it multiple times. - Dododecahedron Blog This 22 page adventure presents a delightful little romp through a colourful town, a dreadful forest, and a small haunted dungeon/crypt. Would that everything I reviewed were at least this good. A credit to county Donegal! - Bryce Lynch (tenfootpole.org)

The abandoned Tower of Ulvarum Orvernus stands atop an asteroid nearly a quarter mile in diameter, located roughly 5 million miles from the planet’s surface. The asteroid maintains Earth-like gravity and a breathable atmosphere, with habitable temperatures. This is all sustained through the harnessed power of a bound Air Elemental and Earth Elemental. If either of these Elementals are freed, the asteroid’s environment will quickly become inhospitable. The PCs may find themselves drawn to the asteroid through a forgotten portal, seeking a way to return home. Alternatively, they might be lured there by rumors of a powerful item or hidden knowledge within the tower’s extensive libraries. A multi-level tower filled with traps and strange encounters including animated armor, alien plant life, giant spiders, and a doppelganger.

In Claine Forest near Padduck Village there has appeared a pit. No-one knows where it came from, it just did. It is not so deep that you cannot see the bottom, but people fear it and avoid it. No-one who has climbed into it has come back, having been dragged beneath the surface by unseen hands. A necromancer has come to the forest, seeking the pit. She does not quite know what she expects from it, but what she hopes for is protection from death. Player-characters may wish to get involved, and thus this constitutes an adventure for old-school systems, for 5-6 PCs of 2nd level 2 or slightly fewer of 3rd. The PCs won’t necessarily all die, and the players will almost certainly survive. Reviews elsewhere: "It pours out flavour in nearly every word, creating delicious situations for the party to interact with. ... We got a village, two rival groups of adventurers, a weird-ass forest, and somewhere in the forest a pit, your final destination. From this, joy is made. Each one of those elements has their component parts well done and, because of this the whole is a wonder." — Bryce Lynch of tenfootpole

No underlying story-hook or rationale for exploring the site is given here. This dungeon assumes that there is a temple somewhere with a mysterious walled-in doorframe in the basement crypt. The walled-in doorframe predates the temple itself and leads to ancient subterranean structures that hint of an older civilization as well as an expansive underworld.
