Algorth, the first fortification in existence, possessed a complexity that would boggle the mind of any immortal. Even Noctis, who had merged half of his soul and essence with this castle, did not know all its secrets. His soul would have to be a thousand times stronger to understand even twenty percent of her mysteries, and if he needed to know more, then the soul power he would need was almost unfathomable.
Sheba, his castle had grown, but she had to give up so much, just like him.
Bringing these two inside of her was a risk, but with what they had achieved, it was worth it, even if the cost turned out to be a hundred times higher. Algorth was made to endure, and it did not matter how much the Primordials beat against her walls; with him inside of it, they would not take a single step inside of it.
This was a task he could not fail, because these two would show him the way to reach the levels of a Primordial!
