The Wilderman was granted the responsibility, by Logos, of keeping this fountain safe from desecration. This was the price that Ronvik had to pay in order to have druidic powers such as animal handling, removing curses, and surviving in the wild. If Ronvik fails to keep the fountain from harm, then he loses these powers and is eternally cut off from Logos. Logos did bring this pool into existence over the course of thousands of years.
In order to secure protection of this fountain, he got the orcs of Korchung to respect him by beating them in many fist-fights. They believed that he must be a god, by his power, earning him the title Dirkrunks (meaning Beast-God). He then explained that nobody can disturb his slumber in the sacred fountain. He then went into the Fountain of Fossils, put in a great number of memories for memories which we have no way of knowing about, and then turned into the wind and disappeared. The orcs believed that he was still bathing and so they protected it with their lives.
The fountain is a 20 foot diameter circular pool surrounding a spiraling fossil of an animal amalgamate. Out of the eyes and mouth of the animal, the water falls. Pillars with a circular structure surrounds the pool, thick with vines that dangle down obscuring the fountain. A humid air fills the area.
The magic of this fountain is this:
While in the water, you can submit memories to gain memories from the pool of equal importance. There is no way of knowing what sorts of memories were submitted into the pool so you don't know what memory will replace your memory.
After so many years of Ronvik supposedly bathing in the fountain, the orcs had forgotten what he had looked like and only remembered figments of the beast form. These descriptions turned to stories orally told to their children. Only the elders of the community would recognize the Wilderman. This is why they believed that Spook was the Wilderman. They had thought he had simply left the sacred fountain when they were not looking . Upon seeing Spook, they all began to worship him and he was able to get them to guide him ''back'' to the fountain.
This fountain was destroyed by Tulach, Spook, and Donaleustopher Arisopholesteipheles XVII, therefore causing the WIlderman to lose his power with Logos and sever any future relationships or deals with this deity.
The reason that the Wilderman put the memory of his deal, with Logos, into the fountain was so that no magic could reveal such a weakness or the existence of the fountain itself. This backfired as the group there took advantage of this weakness.
