HS4 The Forge of Ilmarinen
Ilmarinen the Eternal Hammerer was once widely worshipped by primitive people¸ whom he taught how to work metal. But once they had his knowledge¸ his worship was largely forgotten and his temple declined and was of cousre overrun by monsters. The Forge of Ilmarinen is a short mostly hack and slash OSR dungeon crawl adventure featuring 15 rooms and 9 combat encounters¸ with 11 monsters converted from third edition sources. While primarily intended for first edition and characters 5th to 7th level¸ it is easily used with any OSR game
