The Old Butler
Using my invisibility magic, I sneaked my way across the castle bailey in search of the old butler. With normal mana, this wouldn't have worked, as the Death Realm's power would consume me, but now that I had acquired the power of True Essence, I had essentially become a true inhabitant of this place, thus allowing me to travel freely without Axilia's help.
Although I was not an expert on it yet, after combing its powers with my Chaos's amplification ability, I could pass off as a formidable True Essence user.
Moreover, just because this was the Death Realm, it wasn't just my Necromancy Element abilities that were enhanced. Because everything in this world originated from the Chaos that dwells within me, the Death Essence collected from here would automatically be converted to 'Chaos Essence', which could then be interchanged to any element I wished.
