3858 Waldurk Forest is a Heroica set released in June 2011. It consists of three playable characters trying to get the Chalice of Life from the Dark Druid, and his werewolves and spiders. In addition, there is a stone gray microfigure in the ruins of a pillar. The set also appears to have transparent blue axe blades, similar to the ones Craniac uses in Space Police III.
