Darklight weapon is ancient Aeldari technology?
Am I correct in understanding that according to this description from Ahriman: Undying, the Drukhari darklight weapons are in fact just modernized technology from the War in Heaven?
>Beams of blackness sliced into being in the void. Magenta and cyan haloed them as reality broke along their edges. They struck the necron ships. Matter and darkness unmade each other. The necron ships turned, shivering through reality as they moved. Their hulls were made of material that could exist across dimensions, could slide in and out of being to protect itself. To the weapons of most races in the galaxy that would have made them near invulnerable. The weapons cutting them now were the descendants of those made in the First War. They had been made to kill the undying. And kill they did. The beams of darkness annihilated what they touched, leaving nothing to remake, nothing to phase into unreality.
