Aedis Eclipse is a game based around a group of heroes who end up attempting to destroy Mugen, the Lord of Death. There are three campaigns, one for the Lower Earth, named Greckland, the Surface World, and the Divine world. Each has it's own storyline, and expands on previous storylines. Each world has it's own cast, with some members who return in the next campaign. Items you have earned and unlocked remain in the next campaign, making each campaign slightly less challenging, at least in terms of weaponry.
