Wonder Hole

The Wonder Hole is the name of a gigantic strange system of caverns inhabited by a number of equally strange and often dangerous creatures. However, despite all that, it's most notable aspect is the numerous passages to other worlds, especially the Dusk Realm which was, for a time, partially colonized by Volunteer Soldiers.

The Wonder Hole is situated about 1.5 Km northwest of the Lonesome Outpost, which itself is situated about 35 Km west of Alterna.

History
Not much is known about the history of the Wonder Hole aside from the fact that it's been known for a long time and that despite numerous expeditions it has remained mostly uncharted in part because of its size but also because of how dangerous some part can be.

Because of its mysterious nature, there are numerous rumors on the Wonder Hole some claiming it goes on forever, or that the bottom is connected to another world which would explain the strange ecology of the place. One thing which is known is that some of the creature inhabiting it used to be inhabitants of Grimgar who were forced to flee into the hole and adapted to living there.

In recent history, the most notable events would be:


 * 1) the establishment of a base inside the Wonder Hole by Volunteer Soldiers who were forced to retreat into it by the alliance of Kings' forces.
 * 2) The apparition of a new and powerful race of demi-humans.



Geography
The Wonder hole is incredibly vast and most of it is likely still uncharted territory, in fact even frequently visited zones are still partially unexplored, to make things worst the Hole can sometimes change on its own or through the action of the creatures inhabiting it.

However, 5 zones are fairly well known:

The valley of holes
The zone closest to the entrance, it inhabited by 3 species of demi-human.

The muryan nest
The nest of a monstrous slightly ant-like race of monsters called the muryans.

The kingdom of Devils
A complex system of caverns and buildings, inhabited by Baphomet-looking creatures who, while unsettling, are usually inoffensive.

The Gremlins' nest
The nest of strange harmless bat-like creatures, it connects to both passages to the Dusk Realm and Night Realm.

Melruks
Chickens-like creatures living in the area before the the Wonder Hole.

Demi-humans
The term covers 3 species of humanoids living in the area right inside the Wonder Hole, they're consider to be the weakest creature in the Hole (which is likely false as Gremlins seem even weaker). The 3 will usually kill each other on sight but will attack outsiders first if they think they can win. As such they are considered to be a test of sort for Volunteer Soldiers as they will flee before the powerful ones and attack the weak.

 * 2) Bogies
 * 3) Spriggan

Passages
Despite how strange the Wonder Hole is, its most notable characteristic is probably its connections to other worlds. Rumors speak of the bottom of the hole being connected to another world, and while that could be true, there's no need to go that far to find passages to other worlds. Those passages also seem to be able to appear rather suddenly, unlike all other known passages between worlds which seem to have existed for a very long time.

However, so far only 2 passages are known to exist for sure, and only one of them was shown:


 * 1) A passage to the Dusk Realm, which suddenly appeared and was discovered by Team Haruhiro, however the first to really explore the world beyond were the Tokkis. That passage was later made public leading to an influx of Volunteer Soldiers in the Dusk Realm, however it probable that the passage is now destroyed or at the very least block after the Giant God crushed the exit on the Dusk Realm side.
 * 2) A passage to the Night Realm, it was discovered by Lala and Nono but as that world is apparently incredibly dangerous, almost nothing is known about it. Although, it's possible that the Night Realm and Darunggar are one and the same as both worlds do share quite a number of characteristics, the most notable of them being the constant night.
