Caliban (also known as Arduin Dungeon Number One) was a standalone short story and gaming module written in 1979 by David A. Hargrave and published by Grimoire Games. It was based upon Hargrave’s gaming system known as Arduin. It is the first of only four standalone dungeon books created by Hargrave as an extension of his Arduin Multiverse which at the time of Caliban’s publication was known as The Arduin Trilogy.
