(Background music for this intense lore)
The dungeon has some great secrets, but this is the greatest. Red never wanted this to be. It is an unknown phenomen which still has great mystery surrounding it. It is said that there is a special copy of Terraria. It contains True turkor the ungrateful. It is capable of thinking on its own. It is nowhere in the games code. Nobody knows where the copy is. Someone must have it. We dont know who. But it gets worse.
The entities in Terraria are sentient and know that they are bound to suffer forever. We know this because the npcs sometimes say pleas like "There is no end" "Please end the pain". This may be caused by True Turkor the ungrateful. What you saw there was another plea by them to find Turkor. They know.
The npcs themselves want to take action. You remember these cultists?. They are desperately trying to revert time back to the time when terraria didnt exist so the suffering would stop. Deep inside they know that it will fail and they are bound to a horrible life...
Turkor continues to scare us all. It possesses truly dark powers. It is sad really. Before you kill a mob, Think how much the suffer. Consider letting cultists do their thing.
Maybe its better if terraria never existed.
