Because of the Civil War, prices on various goods increased, causing Schaal and her family to try to become more self-sufficient. Then one day, military intelligence visits William. William is told that has a unique skill. To make sure that Schaal and the other children have a secure future, William decides to go to war. After the Civil War ended, William returned to the village as the Incarnate, Nidhogg.
Those who have lost their souls 
shall be slain by their own.
All jene, die ihre Seelen verloren haben,
sollen von ihresgleichen gerichtet werden.
Los que pierdan sus almas
morirán a manos de los suyos.
Los que pierdan sus almas
morirán por los suyos.
Nous enterrerons de nos mains
nos amis ayant perdu l’esprit.
Chi perde il senno verrà
seppellito dai suoi compagni!
Aqueles que perderam suas almas
devem ser mortos por iguais.
Утратившие разум падут
от рук своих товарищей.
