Merging Flames (Part 1)

On top of that, Lith shared the same energy signature with his Demons, but all he had obtained by combining his strength with them were Thousand Flames. 

After countless hours of training in the Blood Desert, using the tower to protect his cracked life force, Solus had come up with a theory.

"Grandma and Leegaain can use Primordial Flames so it's not something that can only be performed by more than one person. Also, the energy signature is irrelevant as well. Which leaves only one explanation: the secret of Primordial Flames lay in the life force of the users."

"Meaning?" Lith asked with a puzzled look.

"Origin Flames can't be controlled by imbuing willpower in them, only by manipulating the willpower already present in the life force that ignites them. To produce Primordial Flames, you need either an exceptional life force like the Guardians do, or to combine multiple life forces together." Solus replied.
