Lews Therin "Kinslayer"
After the Hundred Companions and Lews Therin sealed the Dark One back up with the Seven Seals, in the last moment the Dark One struck back and tainted Saidin with a darkness that overwhelmed all those channeling at the Bore at that time, driving them instantly mad, to tear up the world and create chaos, ending the Age of Legends .As those men who weren't with these doomed survivors of the assault on Shayol Ghul were exposed to the Taint by drawing on Saidin, these men slowly were consumed with the same madness that turned Lews Therin Telamon into the Kinslayer.
How the Madness works[]
Described as an oily slime or film over the One Power, that is forced to be plunged through to reach the source, the Taint comes back with the power and begins to suffuse the body and spirit, building up in the user until finally they are overwhelmed by it. Described by Nynaeve al'Mera as being spidery threads of black stabbing into the brain of the man who is tainted, creating a network of darkness around the brain and creating the confusion and insanity that grips the man who is consumed by the Taint. How this madness effects different people differs according to their personality and their own actions.
