Thogros

"Thogros" was the name given to the planet Earth by Tkulthe in antiquity, but later evolved to encompass all that existed on that plane of reality.

As a Name
When Tkarmen searched for his sons, he found Tkulthe obsessed with a volcanic world on which life was to develop. Tkulthe introduced the planet as Thogros, and so Tkarmen spread the title amongst the eldritch population until it was well known. Those who were cast out of Tklundesh knew the name of Thogros, and those who came to the planet Egos named it such in memory of Thogros, although the Tying Empire would eventually establish the name "Pamal" to replace Egos.

As a Planet
The planet Thogros is notable for being home to the human race, as well as the resting place of Tkulthe. The name Thogros had been largely forgotten by all but the inhabitants of Tulyon even by the time of Godhos. It was since become known as Earth.

As a Reality
All that exists in the universe soon became known as Thogros when the word was made synonymous with "our world." While in ancient times this definition remained accurate in referring to the entirety of the planet, it later became broader when folk realized that their world was greater than a single planet, and that many other-worldly threats were actually of another reality entirely.

The use of the name "Thogros" has never been cited more than in relation to Formin and other worlds. Wrane explained it to Achsjad in terms of a three dimensional model. His three dimensional model postulated that Thogros ran parallel and intersected Formin, which in turn ran parallel and intersected with the Thrakr demon universe, which itself ran parallel with and intersected with the Abyss. This chain of parallel/pocket dimensions formed a horizontally linear shape, with Tklundesh above Thogros and the realm of Sorgoht, wherein Ayahk's master dwelt, laying beneath Thogros.

The Walls of Creation
In Universe E, the Walls of Creation manifested as crystal barriers on the border of reality, representing the very material of the Thogros concept. It was impossible to reach them unless you could dream of them. They did not really exist, but rather manifested that way in order for feeble human minds to comprehend them. Berny visited this firmament, and observed that beyond the crystal wall there was a storm, and something else moving. The Walls were erected during Universe D by the One, with the apparent purpose of separating the Other from reality.
