Is That What Autonomy Has Done?

The longer a shard is in a certain physical location, like Odeum on Rishar, the more the location and the shard become bonded or become one. I'm pretty sure that it is in the book somewhere that autonomy purposefully sort of sewed a seed of Trell on Scadriel and left it there's dormant in a way. And at any time she could come back and pick it up and develop, cultivate that little seed of autonomy into a new avatar with more power. "Odeum is now part of Rishar and the song of Rishesar and the rhythm of war," says Hidetakaishi.
