Magic Library

Localization
Nothing is known about the exact location of the library besides being in the middle of a forest. It appears to be an isolated area, as no one have been to it in a long time.

Exterior Design
The library is built as an extremely tall, humongous, topless cylindrical tower, with an unique design in it's outside walls appearing like a group of nested curves, with several brick outlines palletized along the building. The library's entrance is a circle shaped gate, designed as a one big cirle in the center and three other circles on each side of the circle.

Interior Design
From the inside, the interior walls are shaped like a hexagon, with numberless bookshelves at each side arranged in various patterns, holding numerous amount of historic books about every known Magic and all related topics. The floors are linked with one of each other with what seems to be bridges, serving as a passageway between sporadic flats in the library.

It was shown to contain four warehouses at the four directions (North, South, East and West)

Notable Events
In Fairy Tail's quest to retrieve the Infinity Clock parts, Erza Scarlet, Wendy Marvell, Carla and Cana Alberona travel to the Magic Library in order to find the missing clock part but their search is obstructed by the Jiggle Butt Gang in an attempt from them to steal the treasure Fairy Tail is looking for. After Wendy fails to persuade them to leave thuggery, the leader requests Erza to wear one of the gang's uniform, in which she finds comforting. Erza then starts questioning their leadership, vowing to teach those misguided fools as Cana and Carla set off for the clock part. After finding a section of old Magic Books and items, Erza mocks the gang's leader's story of the invention of the gang's uniform and scolds his leadership, asking him to perform 100 push-ups to make an example for his subordinates.

After failing, the leader ,along with the two lackeys, perform their "Gas Butt Triple Ecstacy" against Erza, in which Wendy saves her from it, thus filling the entire area with fart. This leads Cana to lose her balance, discovering a secret passage that leads to the long awaited clock part. After Erza and Wendy are informed of their comrades' discovery, the leader suddenly uses Point Blank Ecstasy at Erza, hitting her with the gas directly in the face. After that the gang steals the part from Cana and Carla, leaving them stoned from the gas. As the latters are running away, they are stopped by Erza in her Wingblade Armor, enraged by ruining her flower, defeats the gang with one slash, sending them away.
