The Grimwald Nox (グリムワルドの夜?), or Nox for short, is the battle in which the Monstrums fought the Lemures born from the negative emotions of the people in Gllia.


Originally, the Nox was a gift by the Norse god Grimnir to the people of Gllia. It converts their negative emotions into Lemures, the monsters of the Nox. Then Grimnir sent his demigods to slay them.

In Game[]

The Nox battle is basically the raid battle in Ys IX: Monstrum Nox: Adol and the party need to defend the Sphene in the battlefield from the monsters. Some Nox are mandatory to beat in order to progress further in the Balduq.
