A Kingdom made of Trees. Trees that reach higher than mountains. Death mana density is so high that even the darkest creatures get eaten here before they could do anything.
If you are not a plant creature or anything related to that, then you may as well forget to come here.
Or unless, of course, you are an S5-Grade or higher. Then you will have a chance to stand against most of the beings here easily.
Walking deeper and deeper into the Forest, I kept moving towards the core of the Herbarium of Decay, where the city of Biomechanica was located. It was a city made up of plants that have transmuted into something beyond what is either a monster or a plant, to be honest.
"Who are you? And what purpose do you have here?" A voice came out of nowhere as I kept running. It's probably a forest guard or something that has sensed me or something.
