The Tower is the primary location in The Grinns Tale. It is divided into floors, with each floor consisting of 3-5 rooms. The monsters in the rooms are preset. As with all locations, a floor must be completed for the next floor to be unlocked. The tower currently has 52 floors, much more than all other locations combined (the infinite dungeon not included). The Tower also contains all the artifacts needed to unlock the buildings.
The Tower is the focus of the plot, said to be the source of all magic and of the monsters that terrorize its surroundings. The Brave Hero once sealed himself inside The Tower with the monsters, thus sealing the tower's magic away. Shortly before the game's plot begins, The Tower awakes.
