you were walking in the cave ya know doing the usual! mining, fighting mobs off and usual Until you approach the deep dark biome.. You had too stay very quiet or you might awaken the wardens there was some chests maybe it had good loot? It's best too check or you might miss out so you sneak over and open the chest the noise of the creak from the chest made the wardens let out an croak but go silent again

you grab the loot and close the chest which made another croak come from them before silence you continue your adventure hoping you don't accidentally wake them from their slumber
