The Chapel Tower is a vast chapel area located in the Circle of the Moon series, consisting of large halls and long hallways. It can only be exclusively accessed via the Eternal Corridor.

Intricately beautiful stained glass windows add the atmosphere in the area, making it a worthwhile scenery among players. Regrettably sad to say, this view has become tainted with the appearances of various beasts which have desecrated the sanctity of the holiness of the chapel, especially Andramellech.

While one may often consider the Chapel Tower outright useless after navigating most of the area, there are some notable exceptions. For one thing, the Battle Arena can only be visited through the chapel, and the area has its own warp zone.

Also, given the fact the player has not yet acquired a single card in-game, the Chapel Tower houses possibly the most enemies in the game regarding card drops: the Bomb Skeleton (Salamander), the Heat Shade (Jupiter), the Bloody Sword (Mars), the Thunder Demon (Manticore), the Were-Panther (Thunderbird), the Arc Demon (Apollo), and the Fallen Angel (Saturn).
