Well that's actually the heart of my theory that magic does really exist in the wormverse, its just that the Worms learned it from a species they passed by and its all mixed up with the other stuff they have. Also its the reason I think that Smurf could learn magic from someones mind the same way that she can learn tech. Also I'm fairly certain that Behemoth and the other endbringers being able to sense her might have been an effect of how they all view the world with deranged senses. Either that or a programmed in immunity attached to one or the other shards.
