Sovereign of Finality

Kurumi and Akira, shut-in siblings with no future, only had one glory in life: Dungeon Forge, the game where they built the unbeatable Grand Tower of Ourolith. On the day the servers closed, they woke up not in their room but in another world, with their entire tower brought to life. Cosmic guardians, deadly traps, endless labyrinths—everything they created now stands real. As the feared Kaliburz and DollMaker, the siblings must face kingdoms, races, and powers that see their tower as a threat. Why were they brought here? And in this new world… will they reign as rulers, or be remembered as destroyers?
