Arcana Creations has released the S&W adventure, The Vile Worm, for free. It's a conversion of the DCC adventure of the same name published by Brave Halfling, which itself was a conversion of The Vile Worm of the Eldritch Oak, which was included in the Swords & Wizardry White Box boxed set by none other then Brave Halfling.
So yes, The Vile Worm conversion for Swords and Wizardry is a conversion of a DCC RPG conversion of a Swords and Wizardry White Box adventure. Talk about returning to one's roots.
It's free, it's low level and should occupy a few hours of gameplay on a Saturday night.
From the blurb:
Deep within the forest, an ancient oak has grown huge, twisted, and evil. Ages ago, a savage cult haunted these woods and this tree became the focus of their unspeakable rites. Below it, they carved out a chamber of sacrificial horror where innocent victims were offered to a hideous worm-like god. As the centuries passed, the cult faded into the mists of time, but the twisted old oak stood fast, awaiting the day when the creeping evil in the dark below would be summoned once more.
