Fallen

When you die, your stuff scatters across the ground and ticks down to nothing. Fallen changes that. Your body stays where you fell — a corpse wearing your own skin — and it holds everything you were carrying, right down to your experience.

Walk back, right-click the body, and take your gear. Everything returns to the slot it came from: armor back on as armor, offhand back to your offhand, hotbar to your hotbar. In a hurry? Sneak-right-click to sweep it all back at once.

What it does

Your body, your skin. The corpse renders as you — matching your wide or slim model — lying flat where you died. The owner's name is on the loot screen, not floating over the world.
Everything is kept. Your whole inventory and your XP go into the body. Nothing scatters, nothing burns.
Items go back where they belong. Reclaiming returns each item to its original slot.
Yours first. For a grace period only you (and server operators) can loot your body. After that, anyone can.
It ages. Left alone, a corpse eventually turns to a bare skeleton — a visual cue that it's been there a while.
Nothing is ever lost. A body left far too long drops its contents instead of vanishing, and it won't fall into the void or burn up in lava on its own (both configurable).
Death History — press U. A built-in moderation and recovery tool. Every death is recorded permanently. A green check means the body is still out there; a red X means it's gone. Open any record for a read-only snapshot of exactly what was carried at the moment of death — accurate even after the body was looted. Operators can review any player's history.
Configurable. Grace period, despawn time, skeleton timer, keep-XP, operator override, void/lava behavior, and history size all live in config/fallen.json.
