I moved the Fabric version of this mod, to here.

Provides a bag which can be used to retrieve the player's inventory after death. Inventories are stored on death in a first in first out manner so each time you open a bag you will retrieve items from your earliest unclaimed death. Options for obtaining the bag are configurable and include crafting, dropping at the death site, and dropping on the player's bed (in some versions). Server owners or modpack/adventure map makers might come up with other ways of delivering the bags to players. This mod also includes a craftable gem that allows the player to store and retrieve experience.

Both the bag and the gem can be disabled via config.

Please be aware that this mod disables player inventory dropping on death, so if it installed and none of the config options for obtaining a death bag are enabled there will be no way to get your stuff back without op!

Additionally, I think this should go without saying, but just incase: This mod is not compatible with gravestone mods, or probably any other mod that does stuff with your inventory upon death.
