One second you were in class. The next, you're standing on an endless plain under a sky the wrong shade of blue. The school building is still here, but everything else is gone. No city. No roads. No other humans anywhere. Just 500,000 stunned students, a ring of jagged mountains on the horizon, and something howling from the other side of them. System windows are popping up everywhere. People are reading their classes out loud. Warriors, mages, healers - the crowd is already clustering into groups. Someone is already shouting about forming a government. Then your own screen flickers on. No combat class. No magic. Just: BUILDER SYSTEM - CRAFTING UNLOCKED. While everyone else got a weapon, you got a blueprint. The question is whether that's a death sentence or the thing that will keep you alive. People start cutting down the nearby forests and building, you need to find a group quick. A wall is erecting between two main factions, and you need to go on one side quick.
