Against Terraldia's Fall (Isekai but Everyone from Earth Was Summoned)

Welcome to \"Terraldia,\" a realm where nightmares seep into reality. Luno, a young man with no memory, finds himself torn from Earth and thrown into this harsh world. But unlike other tales, he’s not alone; countless others from his home world have also been summoned, each bearing their own burdens and wielding cursed weapons known as \"cursions\"—instruments of immense power that come with a \"dark cost\".

As Luno struggles to piece together his fragmented past, he discovers that his powers hide more than he realizes. Surrounded by mistrust and betrayal, he must navigate a landscape filled with danger and deceit. Dark forces stir, and Luno grapples with the shadows lurking within himself as he seeks the truth about his existence and the fate of Terraldia—all in, no escape, no second chances, against Terraldia\'s fall.
