Descriptions
When Khaenri’ah was destroyed, a great sinner created endless monsters with alien, dark blood flowing through their veins. They rampaged across the land, destroying all in their paths. Their lives were mutations, caused by powers beyond this world. The black serpentine dragon Durin that attacked Mondstadt was such a mutation.
