The Cavern Of The North & The Northern World

The Cavern Of The North, referred to in Germany as 'Die Nördliche Welt' (The Northern World), is a mythical area that was discovered by a german soldier known as Luis Metzinger brought an expedition to in the early 1900s during World War I. There are many stories to be told about the area, with one thing being certain: It leads to a place deep underground, where a civilization calling itself the Hyperborean live, made up of the very same people that were lead down there by Luis ages ago.

Summary

The basic knowledge about The Cavern Of The North and the subsequent 'Northern World' is that, deep within a certain cavern located in the Arctic; lies a path downward to a massive, underground area. The whole mythological portions of the Cavern comes from how nobody knows who created the caves or why, as despite all appearances, there's several indicators that the caverns were not made naturally.
Within the Cavern and in the center of the Northern World, there are various Artifacts that are found within them that have various functions. The two more noteworthy Artifacts are the Golden Sun and the The Olden Watcher Of Kings; the former of which is located directly in the midst of the Northern World, while the latter is located in the middle of the Cavern. The creator of these artifacts are unknown.
The cave, along with odd stone pathings and carvings that are located within it, has various, massive spikes of Edenite, which researchers have speculated to have existed since before The Bloom even occured. The carvings, speculated to be prehistoric depictions of Humans, depict a massive civilization that once sprawled Earth; one that had three governing rulers along with a supposed deity whos identity remains unknown. The carvings show that, at one point, Earth was connected to three different worlds; a sprawling desert world; a world that exists next to a massive moon; and a completely dark realm with chains rising up high into the sky.
The validity and truth to these depictions are not known.
