Erjat-Reh
Erjat-Reh (Zean: Undying Growth) is a species of lichen native to Aan-Ateki. It has remarkable regenerative properties and its spread is under watchful surveillance by the Nata-Kea tribe.
Description
Singular Erjat-Reh is a minuscule plant, about one centimeter in diameter and almost completely flat. Its surface is green or greyish-green, rough to touch and resembling a porous rock. Bottom of the disc is covered with long, hooked cilia it uses to cling to surfaces. Single specimens are rarely observed, as the Growth's primary characteristic is it's ability to rapidly replicate and form unstable webs quickly covering their surroundings.
Life cycle
The Growth seems to sustain itself on nothing more than sunlight, as water is extremely scarce in the desert environment. In the morning, nets of lichen covering the dunes can be observed, dragging across the sands. During the day, majority of the plants will tear off of the colonies and die due to the heat. As soon as the sun nears the horizon, the surviving units start budding, often in more than one direction at once. It takes about fifteen minutes for a new cell to grow. As the dunes continue to move after dark, the nets continue to rip and seed new clusters of lichen, enhancing their exponential growth. By the end of the night, the population regrows to the previous numbers, maintaining the delicate balance.
Danger
With time, Nata-Kea became worried about the Growth and the possibility of its expansion beyond the desert. Unlike any other plant or animal, it appears to not be constrained by the physical limits of nutrients and body mass in its reproduction. The current hypothesis is that the Growth is the first known species of flora that developed it's own Change. Unfortunately, extrapolating from human history, that means that it's still undergoing adaptation, and if brought outside the desert, could cause unpredictable harm to the ecosystem. It also means that the lichen regularly interacts with Sefia, and that there must be a source of it in the desert. So far, the lichen nets that reached the edge of the sands were small and did not continue to replicate at the normal speeds, suggesting that periods of intense heat or rapid cooling might be necessary to jumpstart the replication. The settlement of Safi-Tor was established, among other reasons, to research the Erjat-Reh biology.
Very creative use of a replicating lichen in a desert environment. I like reading about the dangers it could have on the ecosystem. I’m curious to know what uses, if any, the Nata-Kea have for the erjat-reh.

Thank you! I think the Nata-Kea's priorities right now are, in order: 1. Apparently there is a new continent and price of their main export matrial skyrocketed. 2. The ruins of the lost city they can't figure out how to get into. 3. Everything else. They didn't find any use for the lichen over the last 50 years, but I think that if they spared resources to try to find its source, the desert might hide more surprises. In real life terms, I had no idea I'd add a desert to my Summer Camp world, but I'm happy I did. I had a lot of fun this year, so I might actually work on it a little before the next July, outside of just polishing the drafts after the awards.
