The Orc army, led by the Orc Lord, continues its conquest throughout the Great Forest of Jura. The crisis has spurred Treyni of the Dryads, the caretakers of the forest, to take action. She has had her eye on Rimuru after noticing his rise to prominence in the forest, and she wants Rimuru to defeat the Orc Lord.
The idea that the Orc Lord even existed 
was still just a theory to us...
الفكرة هي أنّ وجود سيّد الأورك بحدّ
...ذاته ما زال نظريّة بالنسبة لنا
Alleine ob ein Orklord existiert,
Que el Orc Lord existiera
solo era una teoría para nosotros.
Que el Orc Lord existiera
solo era una teoría para nosotros.
Mais l’existence même du seigneur orc
n’est encore qu’une hypothèse.
Devo dire che supponevamo
A ideia de que o Lorde Orc existe
ainda era uma teoria entre nós...
А ведь мы только предполагали,
что на свете появился лорд орков…
