Hey, so I'm trying to write a fun fanfiction, but I want to include the integration stage into it as a big role. does anyone know anymore about it, or am I best just taking a shot in the dark? (also, would it be possible to purify mana before forming it into a core? technically, Arthur skipped a big step by pulling the mana together to form a core, and cores are dark because of blood/impurities in the mana, so what if one just made sure there were no impurities before forming the core?)
