Dark Forest was a shortlived Castle subtheme and consisted of only three LEGO sets released in 1996. These sets were not featured in European catalogues, but were nevertheless available at some shops in Europe.
Dark Forest can be seen as a reincarnation of the older Forestmen theme which was discontinued in 1990. It reused the same crest that had already been established for Forestmen in 1987 and its sets also involved woodland hideouts built into hollow trees or rocks. Some Dark Forest minifigures also featured green tunics and forestman hats, very similar to that featured in Forestmen. But all in all, the minifigures offered a greater variety by using different torso pieces and also hoods. Dark Forest did not return after 1996, and was discontinued after only three sets were made, tieing it with Wolfpack for smallest Castle theme.
