Dark Lord (He-Who-Made-The-Dark)

Near the beginning of time and creation, possibly around the First Hytoth, there were two ancient deities originating from SCP-319's dimension, who created both the darkness and the light, He-Who-Made-Dark and his brother He-Who-Made-Light. However, at some point He-Who-Made-Light mocked his brother's creation, causing He-Who-Made-Dark to become angry and attempt to destroy the light. After an extensive battle, He-Who-Made-Light was able to defeat He-Who-Made-Dark by sealing him inside a rock which was banished to the universe of the SCP Foundation, where it began orbiting the Sun of the Sol System, continually exposing it to light which prevented He-Who-Made-Dark from freeing himself.

However, as years passed the meteorite eventually fell to prehistoric Earth, fracturing the continents apart and killing the first people who lived in the sea. Because the Earth went through a day and night cycle, He-Who-Made-Dark would attempt to escape from the meteorite during the night as light was absent, each night making more and more progress and causing massive destruction, until the personification of Earth took notice of him and created the second people to keep He-Who-Made-Dark trapped within the rock by lighting numerous torches around it.

Throughout countless years, numerous savage cults were formed worshiping the brothers, some of which took the meteorite's fractured shards to craft them into objects that could help them summon their deities, with some of these objects becoming SCP-286, SCP-319-1, SCP-719-1, and SCP-1806. In 1894, Sir Bandon Lawhead-Smythe, rival of Lord Blackwood, had found SCP-319-1 and used them to construct a mechanical device that opened to He-Who-Made-Dark's dimension. Wanting to surpass his rival, Bandon went inside the portal, but most likely died as the dimension was unable to sustain life. Left unchecked, the portal began growing which would eventually result in the dimension engulfing the whole universe.

Around 1950, the US Army Corps of Engineers began evacuating several indigenous tribes from islands that were to be used as testing site. However, after the government forcefully removed the tribe who had in their possession the meteorite, the torches burn out, allowing He-Who-Made-Dark's shadow to cause massive destruction similar to nuclear explosions which was apparently covered up as part of the Castle Bravo Nuclear Test. Seeing that this was caused due to the meteorite being left in darkness, the US troopers restored the light over the meteorite. The SCP Foundation soon became involved and took the meteorite under their custody, forming proper containment procedures to keep He-Who-Made-Dark trapped. The Foundation thought of using another SCP to transport SCP-435-1 to an alternate universe, but deduced that this would cause the entity to be freed as he wouldn't be transported along with the meteorite.

When the Foundation discovered SCP-286, game board of Liubo carved from the same material as SCP-435-1, they had several test subjects interact with it, allowing the two brothers to possess them and play against each other while conversing in multiple languages. However, one day He-Who-Made-Dark took possession of Dr. L██ W███ who had been assigned to SCP-286, causing He-Who-Made-Light to take possession of Dr. S███ S████, who had been recently assigned to SCP-435-1, in order to play a game. This was stopped by the intervention of a security team which prevented He-Who-Made-Light from reaching SCP-286, resulting in He-Who-Made-Dark automatically winning and releasing the doctor. Because he won, SCP-435-1 began moving erratically, causing it to impact the ocean basin and leave destruction behind. The Foundation tried to intervene but stopped after SCP-435-1 ceased movement after three minutes.

The Foundation eventually discovered SCP-1806, a sculpture of an elongated human head which caused several anomalous effects to people whose shadows crossed the sculpture's shadow. This effects included: making the person's shadow much dark then it should naturally be before changing shape and becoming inconsistent with the person's outline; following this the affected person would lose their senses becoming partially blind but also gaining the ability to see through other shadows or dark areas He-Who-Made-Dark and other entities residing with him; the person would eventually lose all senses, talking seemingly gibberish and become unable to sustain themselves any longer, leaving them to die if one is present to help them. This had happened to Foundation employee Dr. T. Ellison who was able to see He-Who-Made-Dark and his powers.
