Scarlet King

The Scarlet King is a divine demon, untold amounts of eons old, whom the foundation keeps at bay via Procedure 110-Montauk.

History
The Scarlet King was born with the planting of the Tree of Knowledge, called Khahrahk at the time. He was the smallest of his siblings, but the only one aware, and it brought him great pain. He decides that existence itself is painful and that he'd have no part of it, as well as destroying existence itself. He starts by consuming his siblings and growing stronger on their essence.

He vows to the destroy the Tree, the Creator and the Creation, and consumes or subjugates all the other gods, naming himself King of the Darkness Below. He declares war on creation itself, one which will not end until the very end of everything. He takes Sanaa, one of the gods he subjugates, forcibly as his wife and sires seven daughters on her. Sanaa dies after birthing them, and the King takes his seven daughters as his new brides, sealing them so they would not die as their mother had. From his seven bride-daughters he has seven children called Leviathans.

The Foundation are able to prevent or destroy the first six, but the seventh—the strongest—has yet to be born. It resides in SCP-231 and is stopped from existing by way of the Montauk Procedure.

The seventh gave birth to SCP-999 after O5 ordered to stop Procedure 110-Montuak. O5 ordered the stopping of 110-Montuak to see what would happen, the result was SCP-999.

The Scarlet King's daughters are as follows: A'tivik, A'ghor, A'distat, A'zieb, A'nuht, A'tellif, and A'habbat.
