Vegalta

Vegalta, the Shadowed Calamity is a huge, out-of-spec monster shrouded in mystery. It eats up any sort of data it notices, including PCs and objects, and gets bigger and bigger.

History
Originally believed to be created as a result of The World R:2 breaking down, Vegalta is actually a security program of sorts, designed specifically to devour any broken or hostile data found in the game. How it was created is unknown. It is the cause behind The World's rapid deterioration by constantly consuming any damaged programs.

Trivia

 * Its name likely comes from Beagalltach, a sword from Celtic mythology possessed by Diarmuid Ua Duibhne. Additionally, its second form, Moralta, likely derives its name from Moralltach, the sister sword to Beagalltach.
 * Moralta's body is comprised of a mix of Vegalta's appearance with various powerful monsters from The World's lore, such as Cernunnos and The One Sin.
