A new force has suddenly risen to power in the Great Forest of Jura, and its leader, Clayman, proposes that the Demon Lords hold Walpurgis with the goal of sanctioning the slime who deceived him. Rimuru also begins to prepare for a battle with Clayman, but observing the enemy army's movements reveals that Clayman's target is not Tempest, but Eurazania. Clayman's army will arrive in Eurazania within two days. Can Rimuru's forces get there in time?
Falmuth did have a majin 
named Razen who used magic.
كانت فالموث تمتلك ماجين يُدعى رازين
يستخدم السّحر
Also bei Magie und Farmas kommt
mir nur der Dämon Rasen in den Sinn.
Em Falmuth havia um majin
chamado Razen que usava magia.
Раз речь о волшебниках…
в Фалмусе жил великий маглюд Рейзен.
