!One Block to End All One Blocks

One Block to End All One Blocks is a quest-driven one block survival mod for Fabric 1.21.4. Start with a single block in a void world — break it, and it regenerates with a new drop based on your current phase. Work through 6 phases of escalating blocks, mobs, and quests to progress from a dirt hut to a full survival world built from nothing.
