Once upon a time, there was a knight wearing a suit of black armor and wielding the sword of light. He embarked on a dangerous journey to find the source of evil and cleanse the corruption that was spreading over the world.
The happy ending would be that the knight successfully removed evil, but the source was never cleansed. People became depraved and destroyed themselves in world war. The devastation of this costed many parts of the world, be it people or land.
The miasma has now covered the world in eternal darkness, spreading despair to those that breathe in its mist. Peaceful animals mutated into monsters and the blue ocean turned into contaminated ocean.
It was no use. People tried many methods of solving this problem, be it through sacrifical ritual to summon heroes from another world or submitting to the darkness. Even hell was considered a paradise.
Despair had won.
The collected despair of each natives of the world swirl and mixed into a thick concentration of hopelessness. That soon take shape inside an armor that is buried under the ruins of a fallen castle.
The armor rattles. It seeks an object. A black sword in front of it is coated with dark energy. The armor struggles to move. It slowly crawls towards the sword, taking its dark energy. Once the armor touched the sword, the energy flows into the armor, corrupting it.
The armor is able to move. Its rusted armor turned to black.
It has no sentience. It wander aimlessly in the dark. It arrived in a corridor filled with corpse rats. The corpse rats are busy eating the guts and intestines of the dead. They didn't bother the armor as it walks past them.
A corpse rat blocks the path of the armor, bumping into it. The corpse rat growls and tackles the armor, but the armor swings its black sword, slicing off the snout of the rat.
The rat's cries alerted the other rats. They are enraged at the armor and they begin swarming it. The armor looks at the swarm of rats. Their dark energy fuels the dark sword. The sword craves for more of that fuel. The armor fights the rats until it loses.
The armor is torn apart and chewed into pieces. It took many hours until the armor turned into scraps. What happens now? Is this the end?
The collective despair emerges and swirls into a thick concentration of energy. Slowly, the same armor rises, back from being scraps and returned from where it woke up. The dark sword awaits its owner.
This time, the armor has control. It picks up the sword and the dark energy flows into the armor. The sword craves for more of the dark energy. The armor listens to the dark sword.
It returns to the corridor, with more of the corpse rats eating corpses of people. This time, the armor pressed for the attack and killed three rats in quick succession. This alerted the others and summoned the horde again. In the end, the armor lost again because it is crushed by the sheer weight of the number of rats piling on top of it.
It turns out that whenever the armor gets defeated, the collective despair restores it back to its awakening, with its experience remaining intact. The sword hungers for more dark energy and it strengtens the armor.
From time to time, the armor's skill grew sharper. It kills the swarm of rats better than the last time it fought them. Soon, the armor developed a skill, to dodge attacks. It starts avoiding taking damage so it can last longer in a fight. Still wasn't enough to wipe out all of the corpse rats.
Again and again, through trial and error, the armor fights, strategies, and progress without stopping. Soon, it asks itself, what its purpose. The sword only craves for more power. But that was not what the armor is thinking.
Something forgotten but meaningful. The armor wants to find out what it is. And in order to do that, the armor needs to leave this prison. And for that to happen, the corpse rats must be eliminated.
After a hundred tries, the armor emerges victorious against the swarm of rats. The sword feels pleased for the fill of dark energy that was harvested from the battle. The armor's control over its body improved alot. It can move normally like a human can do.
The armor sees the purple sky for the first time upon leaving the ruins of the castle. The world is in its ruined state. Miasma is spreading all around and there are more monsters roaming around the dead forest. The monsters didn't bother the armor as they don't sense anything. The sword wants more power to harvest but the armor refuses and wants more careful approach. The sword doesn't like that but it couldn't persuade the armor. The armor listened enough of the sword ranting. It earned itself some sentience.
The armor enters the dead forest. The trees are dead and the planta are rotted. The monsters either behaving themselves or tearing each other to claim authority over a territory. The armor moves subtly. The sword is getting impatient.
Angry at this, the sword focuses its energy to fully envelop the armor. The energy forces it to move according to the sword's wishes. The armor attacks every monsters within the line of sight. This continues until a stronger monster appeared and crushed the armor into a chunk of scraps.
Once again, the armor returned from its awakening point. Back to the start. The armor hears the sword's voice, prompting it to be picked up. The armor mindlessly stares at the dark sword. It is the cause of its many downfall. The dark sword is simply too dangerous to be used.
Ultimately, it decided to pick up a random sword. A rusty steel sword. The dark sword asked the armor to reconsider its choice. But the armor shunned the dark sword for not giving it a choice in the first place. Resentment grows and the dark sword swores that it will regret not picking up such treasure. For the first time, the armor thinks it chosen a good choice, and it thinks it feels good.
The armor still fought the corpse rats. Its skilled swordfighting allowed the armor to emerge the same victory without getting hit. The dark energy dissipates and some entered the armor. The dark energy strengthens the armor the same way it strengthens the dark sword.
The armor starts to leave the ruins early and this time, it manages to meet someone in red hoodie and a basket. She asked, "Who are you?"
