Moridana (NPC)

While she shows contempt for most forms of natural life, the mad scientist known as Moridana fetishizes monsters and the transmutation of life. She is the darklord of an underground realm so massive it's easy to miss the fact it's a cavern. Moridana's domain encompasses a number of above-ground biomes, such as forests, aquatic environments, swamps, and mountains. It also has weather phenomena like clouds. The domain has a "moon", although this satellite is actually Moridana's headquarters. The moon leaks radiation, which can mutate the life below. Due to her influence, the domain is filled with warped and feral humanoids mutated by the moon's energy.
