Madness - Core - Tribulation -World Energy Due to his second tribulation Lith could use the world energy to shape an artificial core to Protector. Thrud showed us that the Arthan Madness created mana organs in her body that she altered to make new auxiliary cores in her body Nalrond saw the Arthan Madnessess as a way to mend Lith’ s life force. How about this: The study of A. Madness reveal that the machine uses the elemental energy of the mana geiser to be powered up, while the world energy merge with the subject, and that is what makes the vortexes. Knowing this Lith ’s uses Demon Grasp with his eyes, takes control of the world energy and like he did with Protector, he uses it to mend his life force. The secret is discovered by the study of the A. Madness, but Lith’s dosen’t need to use it.
Horsemen - Merge - White Core Baba Yaga said to Dusk that the resonance between the horsemen and they hosts can surpass or be equal to a white core. If Solus and Lith get to that point, she will receive enough energy to sustain her body. My bet is that this will happen first, in this state they will study their body and notice the increase of auxiliary cores (Solus’s auxiliary cores + Lith’s). Than Lith’s will use Demon Grasp with his eyes and use the world energy to create new auxiliary cores in both bodies.
