The immortal devourers wanted to avenge themselves on both mortal and immortal beings. They sought countless souls to consume and increase their power, becoming even stronger. They were Zacrathis, beings far more powerful than demons. The Ethergeist Academy is located in Vienstorian City, a city in Myrathis, renowned for producing top-tier wargeists who could later protect the Orthelis (earth) from the attacks of evil creatures. The Ethergeist  Situated on a country named Vienstorian, the academy comprises numerous buildings, with the main building atop a castle-like mountain, dominated by dark blue, gold, and black. The academy's students come from different countries and also from various countries. Later, a magical animal named "seltzer" will come with a letter stating that they will be students at the academy. The animal can open a portal so that students can go to that academy. No ordinary people could enter the academy's territory because the academy was protected by magic and animals and magical creatures, so that no evil creatures could destroy the academy. ------
