Ok Aginor created trollocs by taking a human being and blending them with animal DNA hence their the way they look, well what would happen if you took a human being that could channel and mixed it with the animal material? Why was no trolloc ever created that could channel? Admittedly they're to stupid to use the power but in theory it would only require one or two trollocs because they breed true, so they would pass the ability to their offspring like humans do and create an army of super trollocs. However this is still fairly useless because they're still to stupid to use he power but with increased numbers they would create something useful, a Myrddraal that could channel and even though they're random throw backs if enough trollocs channel then they could produce enough Myrddraal. As to how it would work, well to take the terminology off the forum; the human would need to be a born natural channeler or a born teachable channeler that had formed the body soul bridge. This means that the human stock must be able to channel at the time of the conversion (to a trolloc)and as long as the "spark" was not tainted by the transformation the desired result would be achieved. This of course could then lead to another idea, shadow spawn that can channel the True Power... the possibilities are vast.....

So i guess my theory is that it should be possible to have channeling shadow spawn but for some reason i cant see we dont.
