Hey-hey! White Rabbit here! Lammy scanned this article and said it contains unmarked spoilers for all Kiseki games. Turn back now if you don't want to get lasered! OK, byee!
Operation Jormungand (ヨルムンガンド作戦), also known as the Earth Dragon (大地の竜), is a Erebonia-led operation, on the surface the objective being to "put the Calvard Republic to death".[2] Operation Jormungand is said to be the largest conquest operation in the history of Zemuria.[2] The operation is Erebonia's response to the attempted assassination on Emperor Eugent III.

In reality its goal is to eliminate the curse of Erebonia.


Conscription for Operation Jormungand begins on 1 August, S.1206, the day after the Central Council of Erebonia passes the National Mobilization Law unanimously.[3] The conscription targets male citizens between the ages of 19 and 45.[3][2]

  • The name "Jormungand" is derived from the world-swallowing earth dragon from fairy tales.[4]
