Marvolo sighs, rubbing his forehead against a headache he knows won’t come as this time he had the sense to take a preventative potion. Unlike the late Albus Dumbledore’s expectations of him, Marvolo is no Grindelwald to not know his limits. The British Isles and attachettes he can handle but waging war on the entire world was folly. Grindelwald showed that; Hitler and the economy of the Third Reich showed that. History matters and he’s done his best to learn from it despite the complications of the horcruxes limiting him for... too long.
