Lake Bresha

Lake Bresha (ビルジ湖, Biruji-ko, aka Lake Bilge) is a location in Final Fantasy XIII. It is a huge lake located on Cocoon's outer-rim, directly underneath the Hanging Edge. Lake Bresha was completely crystallized when the fal'Cie, Anima, crash-landed there after being defeated by Lightning and her companions.

Datalog
''Lake Bresha is located near Cocoon's outer rim, directly beneath the Hanging Edge. Once a bustling center of activity, this desolate area is now home only to monsters that lurk amongst the centuries-old remnants of civilization.''

''The final wave of power released by the falling Pulse fal'Cie has locked the waters of the lake in solid crystal form, creating a beautiful and unsettling landscape. ''

Story
The characters arrive in Lake Bresha shortly after the events in the Pulse Vestige to discover that they have all become l'Cie. They try to figure out what their Focus is but only manage to discover they all shared the same vision of Ragnarok attacking the Sanctum capital of Eden.

After finding Serah's crystal stuck in a bigger crystal structure, Snow desperately tries to break her free. Lightning leads the other team members away to look for another way out of the crystal lake, leaving Snow behind. They soon arrive at the Bresha Ruins city where they fight a Garuda Interceptor and find an airship to make an escape before their ship is shot down and they crash somewhere in the Vile Peaks.

Meanwhile, PSICOM finds Snow and outnumber him before the Shiva Sisters are summoned and wipe the soldiers out. Snow is forced to face them in a battle to prove his worth to the Eidolons. He defeats them but is apprehended by an unknown group of soldiers, and meets Oerba Yun Fang who takes him captive along with the crystallized Serah. He departs Lake Bresha on board a Cavalry airship.

Trivia

 * Lake Bresha several similarities to Lake Macalania from Final Fantasy X as both have ruins - first caused by the War of Transgression, while the other's are from the Machina War - and both were frozen by mystical beings - Lake Bresha was frozen by Anima's fall, and Lake Macalania is frozen due to the Fayth at Macalania Temple.
 * In Final Fantasy XIII, the Bresha Ruins are divided into two areas: "A City No Longer" and "Echoes of the Past".
 * The architecture of the Bresha Ruins is similar to Hanging Edge, another ruined city abandoned in the aftermath of the War of Transgression.
