In Knife of Dreams the wounded Hero Rand became maimed as well when Semirhage burned his hand off. He had told Min that he would rather lose an arm than hurt her
"Trust me, Min. I won’t hurt you. I will cut off my arm before I hurt you.” She was silent, and he finally looked down to find her peering up at him with a strange expression.and that is what happened: he would not dodge the attack because Min was right behind him. (Her reaction to his declaration suggests that she had a viewing of Rand losing his hand.) Rand sacrificed his hand to Semirhage just as the Norse god Tyr did to the monstrous wolf Fenrir (see Rand essay).
“That’s very nice to hear, sheepherder.” Her voice was as odd as her face.

So far we have one maimed Hero, modelled on one-handed gods like Tyr and Nuada, but there are likely to be two maimed Heroes, since Mat has many parallels with Odin (see Mat essay) and Odin sacrificed an eye to gain knowledge. Mat is about to go to an Otherworld noted for its access to knowledge (and mysterious items). The woman he is on a mission to rescue there has always been the embodiment of knowledge – even if in the past it was incomplete or faulty knowledge. I have theorised that Mat will lose his eye in the world of the Finns (here).
Since the number three is so important in the Wheel of Time, will the third ta’veren also be maimed or at least suffer a chronic wound?
So far Perrin has been hale and whole compared to Rand and Mat. Rand is wounded because he is one with the Land and the Land is being blighted by the Shadow. On the other side of the coin, Rand’s corrupting link with Moridin is also affecting the Land adversely. The loss of his hand represents Rand's (hopefully temporary) loss of strength and humanity.
Mat’s wound – his broken bones and aching hip sustained in Ebou Dar – are a symbol of his dread of the One Power. Eyes are symbols of awareness, vigilance, foresight and honesty, while covered eyes can be a sign of deceit. Mat means to trick the Finns to rescue Moiraine and may lose an eye as a consequence.
If Perrin were wounded it would represent his fear of losing his humanity or those close to him. He would do whatever it takes to avoid either.
Perrin has parallels with smith gods and many of them are lamed, usually by those who force them to work for them. In The Gathering Storm there has been some emphasis on Perrin feeling unable to run and jump freely with the wolves in the Dream:
'Jump down, Young Bull. Jump. It is safe.' As always, the Sending from the wolf came as a mixture of scents and images. Perrin was getting better and better at interpreting those — the soft earth as a representation of the ground, rushing wind as an image of jumping, the scent of relaxation and calmness to indicate there was no need to fear.He has ‘hamstrung’ himself. Wolves usually do the hamstringing rather than be victims of it. I wonder if this isn’t an indication that Perrin will be grievously wounded in the leg. Legs represent strength and stability, both of which are important features of Perrin's character.
'Times before, you always rushed ahead, like a pup newly weaned. Jump. Jump down!' Far below, Hopper sat on his haunches in the field, grinning up at Perrin.
Perrin ground his teeth and muttered a curse or two for stubborn wolves. It seemed to him that the dead ones were particularly bull-headed. Though Hopper did have a point. Perrin had leaped before in this place, if never from the sky itself...
'Run,' Hopper urged, obviously confused at Perrin's reluctance.
"I can't," Perrin said, stopping.

The Shadow would really proclaim its strength if it could strike or even cripple the most life-affirming and least destructive of the three ta’veren.
