From the publisher information:
In 1984, a cult classic RPG was released: Maelstrom by Alexander Scott.
Featuring a historical setting, ordinary people as characters, the original freeform magic system and an extensive herbal section, this game sold huge numbers of copies around the world. Long out of print until Arion Games revived it a few years ago, Maelstrom nevertheless held a special place in the hearts of many gamers.
And now, Maelstrom returns in a brand new edition: Maelstrom Domesday. The game is set in England in the year 1086, still suffering the aftermath of the Norman conquest twenty years earlier. The characters are “special agents” for a powerful Norman Baron, investigating the strange and unusual for a handful of coin, their only qualification being that they have themselves experienced a strange event!
