"A giant, ancient mana stone which remains a mystery to everyone whether it's man-made or not. It's been generating Mana for a long time."
The Ancient Stones is a building which passively produces Mana Stones which can be claimed by the player. It produces at a rate of 540 mana/hour, up to a maximum of 3000 Mana Stones. Its production rate can be boosted by the Mana Fountain, and its maximum storage can be raised by building the Fairy Tree.
