Operation Jormungandr (ヨルムンガンド作戦), also known as the Earth Dragon (大地の竜), is an Erebonian-led operation with the objective to "put the Calvard Republic to death". Operation Jormungandr is said to be the largest conquest operation in the history of Zemuria. The justification of the war effort was framed with the assassination on Emperor Eugent III by alleged Calvardian agents.
In reality its goal is to eliminate the curse of Erebonia.
Conscription for Operation Jormungandr begins on 1 August, S.1206, the day after the Central Council of Erebonia passes the National Mobilization Law unanimously. The conscription targets male citizens between the ages of 19 and 45.
