Claiming

The act of taking telepathic control of a Sundered One. It requires training and willpower, and that training is one of the key purposes of the Academy. Claiming is only possible because Sundered Ones are what the humans call “broken;” something is very wrong with these creatures, and a human with steady, strong concentration can impose their will. It can go wrong badly wrong, but even when it works, the Sundered One always dies in time.

It can go wrong in two ways: Slip the Leash and Reversal. It should be noted that in time, the claimed Sundered One always dies – and that isn’t considered going wrong.
