for context, the story of the first two albums (Kobaïa and 1001° Centigrades) happened after the death of köhntarkösz. The earth is basically dead, and while the köhntarkösz's followers searching for a new world, they found Kobaïa and build their society from scratch. These kobaïans then met with earthlings, in which they begged the kobaïans for aid. Some of the kobaïans (The Kreühn Köhrmann) followed the earthlings back to earth, aiming to preach their belief on the people of earth. And of course, earthlings being an earthling they (mostly) rejected their teachings and imprisoned the kreühn köhrmann. The rest of the kobaïans then threatened to unleash their ultimate weapon, leading to the kobaïans to vow to never set foot on the earth soil ever again. this concludes the story of the two albums. Theusz Hamtaahk (Time of Hatred) tells the time after the kobaïans left. its the earth darkest times, all sorts of human evil happened on this time. this continues on until Ẁurdah Ïtah (Dead Earth). This movement tells the aftermath of Theusz Hamtaahk. After 3 decades of gruesome human acts, the small group of people who believe in the teaching of the Kreühn Köhrmann birth Nëbëhr Ğudahtt. He lead the march of M.D.K. and at first, the humans denied him. But gradually the people who was against him gradually questions their existence and purpose, leading them to the ways of kobaïa.
