Hello Aternos Team,
can you please add the Mod "SiberiaMod"?
Link to the mod: https://www.curseforge.com/minecraft/mc-mods/siberiamod
This mod makes Minecraft as it should be: hardcore, harsh, moderately realistic and unforgiving.
Feel the real survival mode! Warning: very hardcore mod! 
This mod does not contain much new content, but it changes the vanilla mechanics of the game in almost all its aspects, making the survival mode more complicated and exciting, giving value to everything that you have in the game.
