The Road to Salvation Begins from the Ruins

Ruins... Flags... Soldiers fell one by one, and another followed... The patter of rain woke Gelb Aaron. Broken memory fragments appear in my mind... I came to this world, where war, famine, and epidemics are spreading. Humans, orcs, elves, demons, and dragons occupy their respective territories, maintaining the ruins of this world that is about to be damaged. Its voice floats in my ears, what should I do to save this twisted world... My name is Gelb Aaron, you can call me Aaron, welcome to join the Red Guard Order... (The story of an ordinary modern person coming to the continent of Ild)
