Ark of Charon

The sacred World Tree has withered, and with it humanity. Now that a new sapling has sprouted, you must become its caretaker and guide it so that life that once was may return. Ark of Charon is a new type of game that combines colony simulation and tower defense, where players embark on a journey to guide a giant, beast-like sapling of a World Tree to its nursery. Players take on the role of the tree's caretaker, controlling familiars and turning the tree into a fortified mobile fortress as they progress on their journey.
