You see a stone carving.


Yalahar (Inner City, here).


It shows how the Yalahari's intelligence eventually caused the downfall of Yalahar. Stone carvings are composed by two objects that are placed side by side, a different text can be written on each of them. You can only read the text if you stand within three fields of it. Although a version of this stone carving placed on a wall facing east does exist, it hasn't been found in game yet.
In Yalahar Central Building, you can read the following text on the west part of the carving:

In Yalahar, the ancient race pursued their quest for knowledge and science. Their power was so enormous and their magic and weapons that advanced that they could repel the attacks of the warring factions with ease. However, this immense knowledge also initiated the beginning of their downfall.

And you can read this text on the east part of the carving:

By analysing the very structure of the universe, their mago-scientists became aware of a 'missing factor' in all world-views, calculations and sciences. All their research hinted at something to be missing from the big picture, something that had to exist as their calculations clearly proved, but yet undiscovered and seemingly eluding comprehension.
