Abandoned Laboratory. It used to be a famous laboratory center in 2010-2017. Used as a center for experiments on humans, elves, animals and many other creatures. However, it's now abandoned due to power cuts and earthquakes that have occurred. There're several experimental objects that're still alive. Among them is the UK. UK is an elf who becomes a seed-bed for tentacle creatures. He gave birth to many monsters from his womb, even though he was male.
