On the distant planet "GHIU-41" there are a huge number of different amazing creatures. The area of the planet is 98% water, so almost all of these creatures live underwater. The main population of this planet is the unique Gnarkla creatures. The Gnarkles have built huge megacities underwater, and their technological development has moved at a tremendous pace in the last few centuries. But every idyll, something tries to destroy it.. As well as friendly intelligent beings, there are more fearsome organisms on the planet. The inhabitants of the planet are afraid to say that name out loud, but I'm writing this diary from the ground, so I'm not afraid! ELODEA CANADENSIS instills fear in all living things because its main ability is to change the molecular structure of water. It literally turns water into a dark matter that strikes all living things. No one knows why it does this because no one has ever survived an encounter with it. But every evil has its weaknesses. And our villain has a problem.. it's her sister! She's omnipresent, because they're an organism!
