Gaven nodded and confirmed, "Yes, it's from the Land of Sealing, trees that died from the erosion of negative energy. This is just part of it; there are three more carts on the way back."
"Although these trees are not native to the Shadow Plane, the negative energy filled within them is denser than many of the natives. Most importantly, it's so thoroughly saturated that the distribution of negative energy is very even. If they were to be made into textile machines, their utilization of negative energy would far surpass that of the current one."
"It's not just the effects of negative energy that matter, but also the wisp of Undead Divinity clinging to them that greatly increases their affinity for negative energy. If these woods were crafted into weapon handles and processed properly, they might very well come with magic attributes related to negative energy, such as draining life or inflicting negative ranks on those they wound."
