— Mordred Deschain
He had two forms, child, and spider-like monstrosity (making him a Were-Spider). He was born with an extreme hunger as a result of his accelerated growth. His spider form consumed energy much quicker than the child form, but was also much more dangerous.
Role in the Dark Tower SeriesEdit
He was conceived with help from a Demon Elemental (disguised as an Oracle) and the Speaking Demon. The Oracle-disguised Elemental took Roland's sperm in The Gunslinger and the Speaking Demon implanted it in Susannah in The Waste Lands. The baby was transferred ("faxed") to Mia using one of the machines in the Dogan.
After Susannah and Mia were brought to the Fedic Dogan, Mia delivered Mordred. Mordred's first act was to eat his mother. During Susannah's escape, she shot one of his spider legs off. He sought refuge within the tunnels and was brought nourishment by Nigel.
Walter O'Dim attempted to manipulate him by getting a hold of his birthmarked spider leg to open the door of the Dark Tower. When Mordred met Walter, the young spider boy sensed his intentions and proceeded to kill him in a rather brutal manner.Mordred would later eat the remains of Dandelo and his horse Lippy. Unknown to Mordred, they were poisonous and would later give him food poisoning. He was greatly weakened by his illness.
While pursuing Roland and Oy he heard his red father, The Crimson King talking to him telepathically from the blacony of the Dark Tower. He told him to kill the last of Ka-tet and then he could rule the chaos with him at his side after the Tower fell. However he was slain by Roland in the fields of Can'-Ka No Rey, with the help of Oy, who gave his life to warn and protect Roland.
Mordred in Arthurian LegendEdit
Mordred Deschain is based upon the Arthurian Legend of Mordred le Fay. Mordred Le Fay was the illegitimate son of the famous King Arthur and Arthur's Half-sister Morgan Le Fay. Morgan would teach Mordred to hate his father. Mordred Le Fay is known as the traitor, who at the Battle of Camlann, fought Arthur and mortally wounded him. In the process, Mordred himself was killed.
