Thunderbird Mountain

A massive mountain floating within a pocket dimension of unknown origin. The mountain is more than 4'000 meters tall. Most of the mountain is engulfed in an eternal thunderstorm that with occasional rain that causes regular lightning strikes on the mountain.


The mountain features three biomes major biomes and many different micro biomes localized to specific parts of the mountain. They flow into each other but there is a fairly clear broder at a specific altitude for each of them. The peak is a alpine desert with rocks covered by snow and permanent ice.

Alpine Peak

A permanent coverage of snow and ice on top of the hard rock formations of the mountain makes it impossible for life to be sustained. There are almost no plants or animals found at these altitudes. Not even the thunderbird dares to setup their nests this far up. The area starts at the snow line and goes all the way to the top.

Alpine Tundra

Between the snow line and the tree line are a few hundred meters of alpine tundra. There are no trees in this area but also no snow fall as it usually rains at this level. Most of this area is covered by short grass, moss, some hardy flowers and herbs and a few small bushes. Various animals live at this altitude like salamanders, flightless birds and an a species with similarties to the chamois.

Alpine Forests

The rest of the mountain is covered by a dense forest of evergreen trees that form a thick canopy. Many of the trees are deformed from frequent lightning strikes. Then they regrow into a new tree after enough time has passed. These lightning strikes rarely cause a fire because of the wet and cold climate with regular rain fall. There are many more types of animals found in this area than in the tundra above.

Floating Rocks and Underside

The lower portion and the bottom of the mountain is surrounded by several thousand floating rocks. How these rocks are floating is not really understood, but it has probably something to do with the static that is regularly released with lightning. It is very dangerous to travel between these rocks as they are constantly moving and lightning arches appear between them. This is where the thunderbird makes their nests. The underside of the mountain is dominated by stalactites. and constantly dropping water and occasionally dropping material as well.

Watercycle & Erosion

There are many small and two larger streams that run down the slopes of the mountain and eventually fall into the void below. There is enough rainfall to keep the water cycle going at all times. There is no dry season or even dry week. If the water is recycled or comes from somewhere else is unknown. What is not restored is the material of the mountain. Although plant growth does create new matter the rocky parts are never replaced. The water streams slowly carry down material making the mountain a tiny bit smaller with every passing moment. The peak is barely affected by this as the lower levels are permanently frozen and do not move much. Still the occasional snow, rock or mud avalance will bring down bigger amounts of materials in one go. At the current rate it will take several thousand years for the mountain to fully collapse.


The origin of the mountain is completely unknown. No explorer and researcher has found any evidence that would indicate that this mountain is from Earth though. The climate, minerals, plants and animals are similar enough to look like that could be the case but genetic and molecular experiments and tests show that there are minor differences. Additionally there really isn't a place on Earth where there would be a mountain missing. A few researchers have argued that the mountain could be from the very distant past and just developed from there in a slightly different way. Nobody has been able to prove this hypothesis in any convincing manner.
