116 Million Years Post Estahblishment
Once home to a atrocious tribe of Long-extinct Harmsters, the desolate woodland has now evolved into a vast forest populated by various creatures, including the Wolfsters (Lycanocricetosapiens nocturnus) last known living descendant of the non-Riplet Ripperoos, and the Wood Riplets (Cricetualis gestaltiana) who have drifted into a cooperative lifestyle with the Altolopes.
Harmsters are fortunately extinct from this planet, as these killing machines, possessing every evil seen in humans, have led to the extinction of countless species. For example, the Hammoths, once widespread, now live only in North Westerna. All non-Meowse Carnohams have also disappeared. The Girats, a basal lineage of Hamtelopes, have become extinct, and their voids have been filled by their more advanced relatives, the Altolopes, a lineage of ungulopes. Similarly, marine predators feared by most creatures, such as Plurodon, and all non-Derelict Seaver species, have long since become extinct. However, just like humans (this time, not a tumor strain, but extinct due to resource conflicts and self-destruction), the Harmsters were unprepared for their own terrible end, and they too were a tumor strain that "zombified" their own kind. Now, that tumor strain has evolved into the Shroomors.
Meanwhile, neither Wolfsters nor Wood Riplets are behaving in such unnaturally extreme and brutal ways anymore, because over time their brains have developed and with the arrival of the decision-making mechanism, these species have evolved to behave just like nearly a normal human. And did you notice this picture on a huge stone here?
On this stone, an Eldtrich god killed a Harmster who once lived in this land by tearing off its arms and legs and taking it to a hell-like place. The reason is that some of the Harmsters resorted to massacre, thinking that the ancestors of the Wolfsters were similar to them, and this caused that ancestral wolfster species (and the living wolfsters) to fear and hate it, so this Eldtrich god killed a Harmster.
