Inside of Igros Castle

Enemies:  1 lune knight (Dycedarg), 5 knights        Guests:  Zalbag (Arc Knight)

Conditions for winning:  Defeat Dycedarg's elder brother!
This is obviously a mistranslation, since Dycedarg does not have an elder brother, defeat Dycedarg instead. ^_^

This is pretty easy, use Orlandu, Meliadoul and Agrias to finish him off. When Dycedarg bites the dust, you'll face the fourth Lucavi , Adramelk.
