Fractured Mind (Part 2)
The black sphere of the Abomination had swallowed the other two life forces to keep them alive. The Divine Beast side, in turn, had wrapped itself around what was left of the human body to shield it from the deathly touch of the Abomination and hasten its recovery.
Yet the fracturings of the Tiamat's life force had affected Lith's psyche so much that the human side had shut itself down to preserve what little strength it had left. Also, the Voidfeather was almost cut off from the Abomination.
With the human life force in shambles, the Voidfeather lacked the necessary strength to fully contain the Abomination and needed to keep his distance. The problem was that doing that limited his ability to communicate with the Void.
